lang/seed7: update to 05_20230913

20230913:
- The parameters of getHttp(), getHttps() and getFtp() have been
  renamed from 'url' to 'location'. A location is a URL without
  http://, https:// and ftp://, respectively. Many thanks to Liam
  O'Brien for pointing out that getHttps("https://example.com/") does
  not work. The documentation has been improved to contain the example
  getHttps("example.com").
- The exit() function has been moved from seed7_05.s7i to the library
  environment.s7i. Many thanks to u/IllegalMigrant for pointing out
  that exit() was not documented.
- The libraries lower.s7i, more.s7i, upper.s7i, archive_base.s7i,
  http_response.s7i, makedata.s7i, tar_cmds.s7i and tee.s7i have been
  added to the library section and the subject index of the homepage.
  Many thanks to Liam O'Brien for pointing out that they were missing.
- The contrast of menus in the Seed7 homepage has been improved. Many
  thanks u/SachemAgogic for pointing out that the contrast was too low.
- The make7 example program has been improved to support C++. Now the
  macros CXX and CXXFLAGS are supported as well as the target .cpp.o
  and the pattern rule "%.o" with a dependency of "%.cpp" (changes have
  been made in make.s7i and makedata.s7i).
- Chapters about the types 'database' and 'sqlStatement' have been
  added to the manual.
- The file to generate a man page for the Seed7 compiler (doc/s7c.1)
  has been improved.
- A test program for time functions (chktime.sd7) has been added.
- The program findchar.sd7 has been improved to support the option -e
  (specify extension) and to allow a search for any char (with the
  option c).
- The program calc7.sd7 has been improved to support the function
  getFtp().
- The program tar7.sd7 has been improved:
  - Wildcards can be used when an archive is created.
    This works even if the OS shell does not support wildcards.
  - Specific members from an archive can be requested when an archive
    is extracted (or when listing archive contents with tell).
- The library tar_cmds.s7i has been improved to support the changes of
  tar7.sd7.
- In lib/comp/int_act.s7i the integer overflow checks created by the
  compiler have been improved. This improvement is used if both factors
  are unknown at compile time and for C compilers that have neither
  builtin overflow operations, nor an option like -ftrapv, nor support
  for 128-bit integers.
- Tests for the improved overflow checks have been added to chkint.sd7
  and chkovf.sd7.
- In the library makedata.s7i, the rule 'name' has been renamed to
  'target'. The library make.s7i has been adjusted to use 'target'.
- In scanfile.s7i and scanstri.s7i the functions getNextXmlAttribute()
  and getNextHtmlAttribute() have been aligned to behave identically if
  there are no more attributes in a tag.
- In htmldom.s7i the function readHtmlNode has been adjusted to the
  change of getNextHtmlAttribute().
- Several improvements have been made in the time.s7i library:
  - The function time() with a micro seconds parameter has been added.
  - The function toLocalTZ() has been added.
  - The functions hashCode(), toUTC(), timestamp1601() and
    timestamp1601ToTime() have been fixed to work correctly.
- In duration.s7i the function hashCode() has been fixed to work
  correctly.
- In httpserv.s7i the functions processHttpRequest() and getRequest()
  have been renamed to getHttpRequest(). The webserver comanche.sd7
  has been changed to call getHttpRequest() instead of getRequest().
- In tee.s7i the type teeFile has been improved to allow writing to
  many files at once.
- The libraries lower.s7i, more.s7i, tee.s7i and lower.s7i have been
  refactored to use camel case identifiers and documentation comments.
- In asn1.s7i the struct asn1DataElement has been changed. Using the
  tagCategory of an asn1DataElement is deprecated now. Use tagType
  instead of tagCategory as tagType is also used in the ASN.1
  documentation. The renaming has also been done in x509cert.s7i.
- The program chk_all.sd7 has been improved to write a warning if the
  execution of a test program fails.
- Tests for hash tables with time keys and values have been added to
  chkhsh.sd7.
- In tim_rtl.c the function timSetLocalTZ() has been improved to raise
  RANGE_ERROR if a value is not in the allowed range.
- In sql_cli.c and sql_lite.c calls of timSetLocalTZ() have been
  simplified.
- The abstract data type (template) to define enumeration types has
  been moved from seed7_05.s7i to the new enumeration.s7i library.
- In drw_emc.c and gkb_emc.c opening a window with a requested size has
  been improved to work correctly if the Firefox window is maximized.
- Logging functions have been added in con_emc.c, drw_emc.c, emc_utl.c,
  gkb_emc.c, tim_rtl.c and tim_unx.c.
- In str_rtl.c comments about the silencing of a C compiler warning
  have been added to strHeadAssign() and strHeadTemp().
- In common.h the definitions of TIME_T_MIN, TIME_T_MAX and
  inTimeTRange() have been improved.
- Documentation comments have been added or improved in ar.s7i,
  archive_base.s7i, array.s7i, asn1.s7i, bitset.s7i, bitsetof.s7i,
  boolean.s7i, cpio.s7i, ftp.s7i, gethttp.s7i, gethttps.s7i,
  hashsetof.s7i, http_response.s7i, httpserv.s7i, idxarray.s7i,
  lower.s7i, makedata.s7i, more.s7i, pkcs1.s7i, rpm.s7i, scanfile.s7i,
  scanstri.s7i, sql_base.s7i, tar.s7i, tar_cmds.s7i, tee.s7i, time.s7i,
  upper.s7i, zip.s7i, tim_rtl.c and tim_unx.c.

    INDEX_ERROR, has been improved to be accepted by clang. A cast to
    the desired type has been added.
  - The code generation for the hash set functions card() and rand()
    has been improved to support temporary sets.
  - Spezialized code is now generated, if the hash set function rand()
    is used with constant sets.
  - The functions strHeadAssign and strTailAssign are used now. They
    are always called like this: aString = strHeadAssign(aString, pos);
- In the library gzip.s7i the functions length() and tell() have been
  added for a gzipWriteFile.
- In the library tar.s7i the function putFile() has been improved to
  check for seekable() before aplying seek().

  and 'ref'. This is done in the library seed7_05.s7i by defining
  IN_PARAM_IS_REFERENCE(varfunc aType).
- In seed7_05.s7i the boolean condition parameters of loops have been
  changed to be defined with 'ref'. This corresponds to the fact that
  changing a condition variable in the loop body can terminate the
  loop.
- The test suite has been improved to increase the code coverage.
- A test program for enumerations (chkenum.sd7) has been added.
- Tests have been added to chkbig.sd7:

    release.
  - In the makefiles the target distclean has been improved to remove
    src/level.h and src/level_bk.h.
  - The program levelup.c has been improved to maintain the file
    level.h. If level_rl.h has changed it will be copied to level.h. If
    there is no change in level_rl.h every compilation of s7 will
    increment the level.
  - The program wrdepend.c has been improved to check if level.h is
    missing. In this case, level_rl.h is copied to level.h.
  - The minor version number of s7 and s7c has been incremented.
- In seed7_05.s7i, forloop.s7i, chkarr.sd7, chkbig.sd7, chkbin.sd7,

lang/seed7: update to 05_20230529

20230529:
- The FAQ concerning break and continue has been improved.
- Chapters about assignment and constants have been added to the
  tutorial, which is part of the manual. A description of the function
  fraction() has been added to the chapter about predefined types.
- The new library archive_base.s7i has been added. This library
  defines common functions for file archives. It currently defines the
  function readDir() which is used by the archive libraries ar.s7i,
  cpio.s7i, rpm.s7i, tar.s7i and zip.s7i.
- In the zip.s7i library the function readDir() has been improved to
  work for absolute paths (by calling readDir() from archive_base.s7i).
- Several improvements have been made in the rpm.s7i library:
  - The signature section digests are checked when the RPM file is
    opened.
  - The payload digests are only checked if the payload is used.
  - Provided and required dependencies are read when the RPM file is
    opened.
- The compiler (s7c.sd7) has been improved:
  - It recognizes if an array index access would always raise
    INDEX_ERROR. This is done for a constant array and with the range
    of possible index values.
  - The optimization of the floating point power operator with an
    integer exponent has been improved. There are cases where the base
    is constant, and the range of possible exponents allows a
    simplification.
  - The optimization of the floating point left and right shift
    operators has been improved. It considers cases where the number
    that needs to be shifted is constant and cases where nothing is
    constant. In both situations the range of possible shift amounts
    allows simplifications.
  - The optimization of A * B ** C with A and B float and C integer,
    has been improved. This considers cases where B is a power of two
    and the range of possible exponents C allows a simplification.
  - It is recognized if the integer left shift operator would always
    raise OVERFLOW_ERROR. Depending on the range of possible values
    for the shift amount and the value to be shifted, this optimization
    is made.
  - The number of checks for OVERFLOW_ERROR and NUMERIC_ERROR of the
    integer power operator has been reduced. Depending on the range of
    possible values for base and exponent, some checks can be omitted.
  - Now the range of possible integer values is determined for the
    expression ord(aBigInteger mod 2_ ** n).
  - Now the range of possible integer values is determined for the
    length of a sub-string.
  - The generated code for 'elsif FALSE then end if' as been fixed.
  - String index checks are optimized away if the range of possible
    index values always remains inside a constant string.
  - Computing the length of a fixLen substring has been optimized
    (e.g.: length(aString[A fixLen B]) will always return B).
  - The optimization of the string length function has been changed to
    sum up the length of the components as integers.
- The test suite has been improved to increase the code coverage of the
  compiler.
- Tests for array assignment, array length and array index access have
  been added to chkarr.sd7.
- Tests of the optimization of expressions like ord((A + B) mod C)
  (the modulus of a bigInteger sum converted to an integer) have been
  added.
- Several tests have been added to chkflt.sd7:
  - Tests for float left shift (<<).
  - Tests for float right shift (>>).
  - Tests for float ** integer.
  - Tests for the A * B ** C optimization.
  - Tests for float ** float.
  - The tests for decompose() have been improved.
  - Tests for ceil(), floor() and trigonometric functions have been
    added.
- Tests for the power operator (**) and for the integer >>:= operator
  have been added to chkint.sd7.
- Tests for the overflow of shift left (<<) and for the power operator
  (**) have been added to chkovf.sd7.
- Tests for string head have been added to chkidx.sd7.
- Tests for empty if-, while- and repeat-statements have been added to
  chkprc.sd7.
- Tests for card(), rand() and assignment have been added to
  chkset.sd7.
- Several tests have been added to chkstr.sd7:
  - Tests for string length.
  - Tests for string index access.
  - Tests for the string head function.
  - Tests for string concatenation.
  - Tests for string assignment.
- The phrase "works correct" has been replaced with "works correctly"
  in the files chk_all.sd7, chkarr.sd7, chkbig.sd7, chkbin.sd7,
  chkbigdata.sd7, chkbool.sd7, chkbst.sd7, chkchr.sd7, chkcmd.sd7,
  chkexc.sd7, chkfil.sd7, chkflt.sd7, chkhsh.sd7, chkidx.sd7,
  chkint.sd7, chkovf.sd7, chkprc.sd7, chkset.sd7 and chkstr.sd7.
- The value STMT_BLOCK_IN_PARENTHESES_OK has been added to confval.sd7.
- The initialization of local variables and constants with a single
  local value has been fixed (in dcllib.c).
- In flt_rtl.c the function fltLdexp() has been improved to work
  correctly for infinity, even if ldexp() does not.
- The program chkccomp.c has been improved to determine
  LDEXP_OF_INFINITY_OKAY (which defines if ldexp() works for infinity).
- Documentation comments have been improved in null_file.s7i.

20230422:
- The compiler option -S to specify the stack size has been added.
  Many thanks to Bruce Axtens for pointing out problems with the
  Ackermann function at RosettaCode. This triggered the -S improvement.
- Many thanks to Bruce Axtens for adding Seed7 to the Exercism project.
  Discussions about that resulted in several improvements:
  - Now call-by-name parameters can be specified with 'in' and 'ref'.
  - Support for syntax statements without $ (dollar) has been added.
  - The error message for an unspecified kind of in-parameter has been
    improved.
- Many thanks to Gary Chike for pointing out problems:
  - The RosettaCode example "Convert decimal number to rational" did
    not work correct. To fix that, the function fraction(), which gets
    a fraction as string (e.g. "1/3"), has been added to bigrat.s7i and
    rational.s7i.
  - Mac OS 13.2.1 had permission problems when installing Seed7. The
    copying of manual pages failed. In mk_osx.mak and mk_osxcl.mak, the
    copying of the s7 and s7c manual pages to /usr/share/man/man1 has
    been changed to allow a failure.
  - On some computers, vim syntax highlighting is turned off by
    default. The FAQ has been improved to describe the steps for
    enabling vim syntax highlighting.
- Explanations about design principles, compiler options, syntax
  highlighting, forward declarations, function overloading, function
  declarations and declaring break/continue statements have been
  added or improved in the FAQ.
- Chapters about function declarations and overloading have been
  added to the tutorial (part of the manual).
- In the manual the chapters about types, parameters and expressions
  have been improved.

  enumeration types.
- The files panic.sd7, wiz.sd7, savehd7.sd7, cards.s7i, sql_base.s7i
  and boolean.s7i have been changed to use the new function literal().
- Support for the ternary operator ?: has been added for enumerations
  and for the types 'type' and 'category'.
- The compiler (s7c.sd7) has been improved:
  - At several places the function integerLiteral() is used instead of
    str() to create integer literals.
  - Assignments to temp variables in inline functions have been fixed.
    This allows: float parse ("0." & "0" mult 307 & "1")
  - If-statements are used in overflow checks for the operators +:=,
    -:=, *:=, <<:= and >>:=.
  - Generated temporary variables have been renamed in int_act.s7i.
  - The code of the factorial function has been optimized.
  - Support for the action ENU_LIT has been added.
  - The action ENU_LIT has been added to the list of special actions.
  - Allocated result data of inlined special actions is now freed.
  - Now integer comparisons are checked with -oc3 if they can be
    computed at compile time. With -w2, a warning is written if this
    is the case.
  - The compiler option -S to specify the stack size has been added.
- In zip.s7i the function fileMode() has been fixed to work for short
  file names.
- The test program chkflt.sd7 has been improved to have detailed error
  messages. Tests for converting between floats to strings in both
  directions have been added as well.
- Definitions of LINKER_OPT_STACK_SIZE and DEFAULT_STACK_SIZE have been
  added to cc_conf.s7i. The file cmd_rtl.c and the program confval.sd7
  have been adjusted accordingly.
- The interpreter has been improved to support the actions DCL_SYNTAX,
  ENU_LIT and PRC_BEGIN_NOOP.

- The error messages "Syntax declared twice", "Associativity expected",
  "Dot expression expected" and "Integer literal expected" have been
  improved in error.c.

  STRTOD_ACCEPTS_INF, STRTOD_ACCEPTS_INFINITY, STRTOD_ACCEPTS_NAN and
  STRTOD_ACCEPTS_SIGN_WITHOUT_DIGITS.
- In gkb_win.c definitions of XBUTTON1, XBUTTON2, WM_MOUSEWHEEL,
  GET_WHEEL_DELTA_WPARAM, VK_OEM_PLUS, VK_OEM_MINUS and VK_OEM_1 to
  VK_OEM_8 are added if they are not present in the include files.
- In heaputl.c the function setupStack() has been improved to have the
  requested stack size as a parameter.

lang/seed7: update to 05_20230305

20230305:
- The make7 example program has been improved to support quoted
  dependencies (changes have been made in makedata.s7i). A warning is
  written if the quoted dependency does not end with ", or when it is
  not followed by whitespace.
- The comanche web-server example program has been improved:
  - CGI scripts with shebang are supported now. Shebang means that the
    first line of the script starts with #! and is followed by the
    command (and possible options) to interpret the script.
  - Now the root directories for HTML files (html-dir) and CGI files
    (cgi-dir) are converted to an absolute path.
  - On startup of comanche, the current working directory is changed
    to the root directory for CGI files (some CGI scripts need this).
  - The new option -c can be used to specify the cgi-name used in the
    HTTP(S) requests. If cgi-name is "", the cgi-name is taken from
    cgi-dir. Without -c, the default cgi-name of "/cgi-bin/" is used.
  - The new parameter env-file can be used to specify a property file
    with environment variables to be defined.
  - The help text written with the option -? or -h has been improved.
  - Definitions of the environment variables REQUEST_METHOD,
    CONTENT_LENGTH and DOCUMENT_ROOT have been added (in
    http_response.s7i). These environment variables are used by CGI
    scripts.
- An explanation about the compilation to a dll/so has been added to
  the FAQ.
- An explanation of the fixLen sub-string has been added to the manual.
- The compiler s7c has been improved to read configuration values with
  the option -c. This allows s7c to be able to switch between
  generating machine code (default) or JavaScript/web-assembly
  (with -cemcc).
- The compiler has been improved to generate better code for insert()
  (insert elements into an array). For arrays of plain values (e.g.
  array integer) unnecessary copying of data will be avoided now.
  Changes have been made in arr_act.s7i, expr_util.s7i, arr_rtl.c and
  arr_rtl.h.
- The library propertyfile.s7i has been improved so that EOF terminates
  a property key or value.
- The functions assignConfigValue() and readConfig() have been added
  to the cc_conf.s7i library.
- In bitdata.s7i the close() function for LSB/MSB bit streams has been
  fixed to also work near the end of the file and for MSB bit streams.
- In bitdata.s7i the function gets() has been improved so that a
  maxLength of 0 sets the position to the beginning of the next byte
  and returns an empty string. If bytePos is beyond the length of the
  string, an INDEX_ERROR is avoided.
- In echo.s7i, editline.s7i, line.s7i, strifile.s7i and stritext.s7i
  the function gets() has been improved to always raise RANGE_ERROR
  for a negative maxLength. A maxLength of 0 always returns an empty
  string.
- In png.s7i reading of PNG chunks has been refactored.
- In gzip.s7i, iobuffer.s7i, lzma.s7i, strifile.s7i, xz.s7i and
  zstd.s7i the function seek() has been improved to raise RANGE_ERROR
  for positions <= 0.
- In asn1.s7i, ccittfax.s7i, cli_cmds.s7i, csv.s7i, ftp.s7i, html.s7i,
  htmldom.s7i, http_response.s7i, makedata.s7i, stritext.s7i and
  wildcard.s7i, appending an element to an array has been improved. Now
  it is done with "anArray &:= element" instead of
  "anArray &:= [] (element)".
- In chkstr.sd7 the tests for the functions lower() and upper() have
  been improved to use expression arguments.
- In chkbig.sd7 tests for the bigInteger sci operator have been added.
- Tests for close() of LSB/MSB bit streams have been added to
  chkbitdata.sd7.
- The program chk_all.sd7 has been adjusted to the changes in
  chkbig.sd7 and chkbitdata.sd7.
- The libraries bigint.s7i, bigrat.s7i, deflate.s7i, elliptic.s7i,
  encoding.s7i, gzip.s7i, inflate.s7i, iobuffer.s7i, lzma.s7i, png.s7i,
  rational.s7i, scanstri.s7i, strifile.s7i, stritext.s7i, xz.s7i and
  zstd.s7i have been improved to use fixLen sub-strings.
- The program bas7.sd7 has been improved to use fixLen sub-strings.
- In s7c.sd7 names of array and hash types have been refactored.
- In bin32.s7i the deprecated functions bin32AsFourBytesBe and
  bin32AsFourBytesLe have been removed.
- In bin64.s7i the deprecated functions bin64AsEightBytesBe and
  bin64AsEightBytesLe have been removed.
- In bytedata.s7i the deprecated functions int16AsTwoBytesBe,
  int32AsFourBytesBe, int64AsEightBytesBe, int16AsTwoBytesLe,
  int32AsFourBytesLe, int64AsEightBytesLe, bigAsEightBytesBe and
  bigAsEightBytesLe have been removed.
- In lzw.s7i the deprecated functions lzwEncodeMsb() and lzwDecodeMsb()
  have been removed.
- In gzip.s7i the deprecated functions openGunzipFile(aFile) and
  openGzipFile(aFile) have been removed.
- In arr_rtl.c the function arrInsertArrayTemp() has been added, and
  the function arrInsertArray() has been changed to leave the
  'elements' array as is.
- The "clean" target of the makefiles has been improved to only remove
  the libraries created by the same makefile.
- The library names in mk_emccl.mak and mk_emccw.mak have been changed
  from *.a to *_emc.a. Additionally, the file ../bin/cc_conf_emcc.prop
  is created, when running make. This allows the Emscripten
  version of Seed7 to be installed parallely to the normal Seed7
  installation.
- The makefiles mk_mingw.mak and mk_nmake.mak have been improved to
  avoid the "file too big"/"too many sections" error.
- Documentation comments have been improved in bitdata.s7i, echo.s7i,
  editline.s7i, keybd.s7i, line.s7i, osfiles.s7i, stritext.s7i,
  tls.s7i, arr_rtl.c, drwlib.c and kbdlib.c.

20230130:
- The drivers used in the browser (when Seed7 is compiled with
  Emscripten) have been improved (in con_emc.c, drw_emc.c, fil_emc.c,
  gkb_emc.c, tim_emc.c and emc_utl.c). Now graphic Seed7 programs can
  be compiled to JavaScript and Webassembly to run them in the browser.
- A new sub-string operation with a guaranteed length (fixLen) has been
  introduced. E.g.: "abcde"[2 fixLen 3].
- 30 libraries have been adjusted to use the fixLen sub-string. The
  guaranteed sub-string length assures that conversions like
  bytes2Int() do not get data that is too short.
- The library zip.s7i has been fixed to work correct if a descriptor
  signature follows the deflated data.
- The library jpeg.s7i has been refactored to use the segment length
  for reading a segment into a string.
- A close() function for LSB and MSB bit streams has been addded to
  bitdata.s7i. The close() sets the the position of the underlying
  file directly after the bit stream. This is used by the function
  inflate() (in the inflate.s7i library).
- The function flush() has been added to the tee.s7i library.
- Several characters in the fonts stdfont10.s7i, stdfont12.s7i,
  stdfont14.s7i, stdfont16.s7i, stdfont18.s7i, stdfont20.s7i,
  stdfont24.s7i, vecfont10.s7i and vecfont18.s7i have been improved.
- Interpreter and compiler have been improved to support the action
  STR_SUBSTR_FIXLEN.
- The compiler (s7c.sd7) has been improved:
  - Support for arcs with thickness has been added (action DRW_PFARC).
  - Code that reports a GRAPHIC_ERROR is now generated.
  - The optimizations for string sub-strings ("abcde"[2 len 3] and
    "abcde"[2 fixLen 3]) have been improved.
  - The optimizations for combinations of sub-string and conversion to
    integer (e.g.: bytes2Int(stri[5 fixLen 4], UNSIGNED, LE) ) have
    been improved.
  - The size of the generated init_values function has been reduced.
  - If requested by USE_DO_EXIT, the function doExit() is called at the
    end of the program.
  - Profiling data is stored in allocated memory instead of an array.
    Some C compilers had problems with the array approach.
- The documentation in doc/faq.htm, doc/faq.txt, src/read_me.htm and
  src/read_me.txt has been updated.
- More detailed error messages have been introduced in chkbig.sd7,
  chkint.sd7 and chkset.sd7.
- Tests in chkint.sd7, chkstr.sd7 and chkidx.sd7 have been improved to
  check the new sub-string function (fixLen) with and without a
  subsequent conversion to integer.
- Tests in chkidx.sd7 have been refactored to use if-statements
  instead of using an ok variable.
- An optional event tracing has been added to con_win.c.
- The event tracing in drw_win.c and gkb_win.c has been improved.
- The program chkccomp.c has been improved to determine
  SYSTEM_RESULT_FOR_RETURN_0 in a way that works also with Emscipten.
- The test programs to determine LIMIT_FMT_E_MAXIMUM_FLOAT_PRECISION
  and LIMIT_FMT_F_MAXIMUM_FLOAT_PRECISION in chkccomp.c have been
  improved to define the large array outside of main (Emsripten
  needs this).
- In common.h the format strings for OS_OFF_T have been changed to
  prefer the long format if sizeof(int) = 4 and sizeof(long) = 4.
- An include of traceutl.h has been added to actlib.c, biglib.c,
  blnlib.c, bstlib.c, chrlib.c, conlib.c, drwlib.c, fillib.c, fltlib.c,
  intlib.c, pcslib.c, pollib.c, setlib.c and strlib.c. This allows
  enabling LOG_FUNCTIONS with strict C compilers.
- The function printSet() has been added to set_rtl.c. This function
  is used in set_rtl.c as replacement for prot_set() when LOG_FUNCTIONS
  is enabled. This allows logging in compiled programs.
- Logging functions have been improved in arr_rtl.c, con_win.c,
  drw_win.c, drw_x11.c, fil_rtl.c and gkb_win.c.
- Occurrances of exit() and atexit() have been replaced by os_exit()
  respectively os_atexit(). This way, the makefiles mk_emccl.mak and
  mk_emccw.mak can define os_exit() and os_atexit() to use doExit()
  and registerExitFunction() instead of the default functions.
- JavaScript specific functions have been moved from fil_unx.c to
  new file fil_emc.c.
- Keyboard functions have been moved from drw_emc.c to the new file
  gkb_emc.c.
- The JavaScript keyboard drivers in con_emc.c and gkb_emc.c have
  been improved to work with synchronous I/O although JavaScript works
  asynchronous in the browser.
- In the new file tim_emc.c the function timAwait() has been
  introduced. This function saves keypresses that happen during the
  wait (it works together with the keyboard drivers from con_emc.c or
  gkb_emc.c).
- The new file emc_utl.c has been introduced. This file contains
  registerExitFunction() and doExit() which replace atexit() and exit()
  under Emscripten. It also defines enqueue() and dequeue() which are
  used during timAwait() to queue keypresses. And finally, it defines
  mapKeyNameIdToKey() which is used by the keyboard drivers.
- Functions to register and execute callbacks have been added to
  pre_js.js.
- The makefiles mk_emccl.mak and mk_emccw.mak have been improved to
  use the linker options ASYNCIFY, ASYNCIFY_STACK_SIZE and
  EXIT_RUNTIME. The new files emc_utl.c, fil_emc.c, tim_emc.c and
  gkb_emc.c have also been added.
- JavaScript strings in the .c files have been refactored to use "
  instead of '.
- The definition of USE_DO_EXIT has been added to cc_conf.s7i. The file
  cmd_rtl.c and the program confval.sd7 have been adjusted accordingly.
- The keyboard driver gkb_x11.c has been improved to work correctly
  when the keyboard layout is switched.
- Documentation comments have been improved in string.s7i, str_rtl.c
  and strlib.c.

lang/seed7: update to 05_20221218

20221218:
- Examples for reading from the keyboard have been added to the manual.
- In src/read_me.txt and src/read_me.htm the description "compiling
  Seed7 under windows with cl from MSVC" has been improved. The
  description of possible C compiler warnings has also been improved.
- Support for the ternary operator ?: has been added to the types
  bitset, color, duration and time.
- The graphic keyboard test program gkbd.sd7 has been improved to
  support super/windows keys.
- Definitions of KEY_SUPER, KEY_LEFT_SUPER and KEY_RIGHT_SUPER have
  been added to the libraries keybd.s7i and keydescr.s7i.
- The tls.s7i library has been improved to reopen a socket if the
  old session cannot be reused.
- In gif.s7i a small error in reading a GIF header has been fixed.
- The compiler (s7c.sd7) has been improved:
  - Unsupported Seed7 compiler options trigger a warning now.
  - Better optimizations for abs(), mdiv and mod are done.
  - More integer overflow checks of abs(), <<, *, div, mdiv, mod and
    rem are optimized away (with option -oc3).
  - More division by zero checks are optimized away.
  - Computing the range of possible integer results for abs(),
    bitLength(), log2(), log10(), sqrt() +, -, <<, >>, - (negate), *
    and ?: (ternary operator) has been improved. This also helps in
    reducing the number of integer overflow checks.
  - The statistics about integer overflow checks and division checks
    have been improved.
  - A warning is written at a catch of otherwise when checks for an
    exception have been suppressed (this is done with -w2).
- The code coverage of the integer tests in chkint.sd7 and
  chkovf.sd7 has been increased. Now, all code in comp/int_act.s7i
  is tested (except code for non-twos-complement computers).
- Several tests in chkint.sd7 have been refactored to avoid
  optimizations that skip tests (Expressions are compared with
  intExpr(value) instead of just value).
- Documentation comments have been improved in time.s7i.
- The graphic driver for windows (drw_win.c) has been improved:
  - Windows are now created with a size that includes decorations.
  - The windows class is registered with with RegisterClassExW() now.
    This triggers the creation of Unicode windows (where keypresses
    return Unicode characters).
  - A function to draw filled chords (drwPFArcChord) under windows has
    been added.
  - An empty window is just created once on initialization and stored
    globally.
- The graphic keyboard driver for windows (gkb_win.c) has been
  improved:
  - The function getc(GRAPH_KEYBOARD) now returns Unicode characters.
  - Dead keys are returned directly and are not combined with the next
    character pressed (this combining can be done by the program).
  - Holding down a windows/super key and pressing a cursor key is
    supported now (this resizes and moves the current active window).
    In this case the program now receives KEY_RESIZE characters (if
    they have been requested with selectInput()).
  - Combinations of CTRL + ALT + letter are now recognized correctly
    (CTRL is preferred over ALT in combinations with a letter).
  - The combination of cursor, function and mouse keys with modifier
    keys now prefers SHIFT over the other modifiers and CTRL over ALT.
  - The recognition of button presses in gkbButtonPressed() has been
    improved to also work for Unicode characters.
  - Now wide char functions (CreateWindowW(), CreateWindowExW(),
    MapVirtualKeyW(), PeekMessageW(), GetMessageW()) are used and only
    correctly received messages are processed.
  - The lowest four bits of a system command (wParam of WM_SYSCOMMAND
    message) are ignored now.
  - Macros are used to recognize mouse wheel and xbuttons.
  - Macro definitions have been added, as some C compilers do not
    provide them.
- The graphic keyboard drivers (gkb_win.c and gkb_x11.c) have been
  improved to support super/windows keys.
- The support for the unused action CHR_CONV has been removed.
- The number of C compiler warnings has been reduced.
- Unnecessary initialisations and assignments have been removed in
  several C files.
- Usages of strcpy() and wcscpy() have been reduced.
- In hshlib.c the hash table for-loops have been adjusted to process
  the elements in the same succession as in compiled programs. The
  code has also been simplified.
- The program chkccomp.c has been improved:
  - Now, a backup copy of the source file (e.g. ctest123.cbak) is
    created if a test program fails.
  - Now, an empty output of a test program is recognized and the test
    is repeated (Some anti-virus software of Windows may trigger this).
  - Now, it considers wasm files for an Emscripten build.
  - The macros os_setmode, os_fdopen and os_fileno are determined.
- Usages of isatty(), fdopen() and fileno() have been replaced by
  os_isatty(), os_fdopen() and os_fileno() respectively.
- Some fixes for Emscripten have been done:
  - The files mk_emccl.mak and mk_emccw.mak have been adjusted for the
    newest version of Emscripten. Now, there is source information in a
    stack trace, and the stack size used by Emscipten has been
    increased.
  - In chkccomp.c wasm files are considered now.
  - The size of functions has been reduced in chkchr.sd7, chkint.sd7
    and chkstr.sd7. This avoids a stack overflow in Node.js.
- Logging functions have been added or improved in drw_win.c,
  gkb_win.c, gkb_x11.c and intlib.c.

Add WWW entries to port Makefiles

It has been common practice to have one or more URLs at the end of the
ports' pkg-descr files, one per line and prefixed with "WWW:". These
URLs should point at a project website or other relevant resources.

Access to these URLs required processing of the pkg-descr files, and
they have often become stale over time. If more than one such URL was
present in a pkg-descr file, only the first one was tarnsfered into
the port INDEX, but for many ports only the last line did contain the
port specific URL to further information.

There have been several proposals to make a project URL available as
a macro in the ports' Makefiles, over time.

This commit implements such a proposal and moves one of the WWW: entries
of each pkg-descr file into the respective port's Makefile. A heuristic
attempts to identify the most relevant URL in case there is more than
one WWW: entry in some pkg-descr file. URLs that are not moved into the
Makefile are prefixed with "See also:" instead of "WWW:" in the pkg-descr
files in order to preserve them.

There are 1256 ports that had no WWW: entries in pkg-descr files. These
ports will not be touched in this commit.

The portlint port has been adjusted to expect a WWW entry in each port
Makefile, and to flag any remaining "WWW:" lines in pkg-descr files as
deprecated.

  have been done with Dosbox.
- Explanations about syntax highlighting, static type checking and
  return type overloading have been improved in the FAQ.

  explain the window close button and window resize events.
  The manual has also been adjusted to describe the new functions
  instead of the deprecated ones.
- The error messages for failed declarations have been improved.
- The error reporting has been improved to also show an error line
  if parsing the file has finished.
- Reading from a Windows console with getc(KEYBOARD) has been
  improved to support all Unicode characters (including characters
  outside of the Basic Multilingual Plane). This allows the reading
  of characters that have been pasted from the clipboard to a console
  window.
- The functions inputReady(), getc(aFile, NO_WAIT), clickedXPos()
  and clickedYPos() have been added to keybd.s7i.

  toUtf16Le(), fromUtf16Le() and fromUtf7() have been added to
  unicode.s7i.
- The functions toUtf16Be() and toUtf16Le() raise RANGE_ERROR if a
  surrogate character is present.
- The functions fromUtf16Be() and fromUtf16Le() raise RANGE_ERROR
  if an invalid surrogate pair is found (a single surrogate character
  or surrogate characters not in the proper succession).
- In unicode.s7i the function replaceUtf16SurrogatePairs() has been
  fixed to work correctly.
- Tests for toUtf16Be(), fromUtf16Be(), toUtf16Le(), fromUtf16Le()
  and replaceUtf16SurrogatePairs() have been added to chkstr.sd7.
- Several improvements have been done in chkccomp.c:
  - If reading a numeric test result fails, the program waits for a
    second before restarting the test.
  - It shows an error message if a test fails to deliver a numeric
    result.
  - It does not create an empty test program. Some anti virus
    software considers an empty program to be dangerous.
  - It determines if partial linking is actually working.
  - A list of potential partial linking options is tested to find
    the correct one.
  - The number of warnings has been reduced.
- In tim_dos.c, tim_unx.c and tim_win.c the function timNow() has
  been improved to work also for an unsigned time_t.

  sudoku7.sd7, tet.sd7, tetg.sd7 and wator.sd7 have been altered
  to use inputReady(), getc(aFile, NO_WAIT), clickedXPos() and
  clickedYPos() instead of the deprecated functions.
- In keybd.s7, the implementation of getc(aFile, NO_WAIT) is now
  based on inputReady(). The primitive actions KBD_BUSY_GETC and
  GKB_BUSY_GETC are not needed anymore.
- The support for the primitive actions KBD_BUSY_GETC and
  GKB_BUSY_GETC has been removed from interpreter and compiler.
  Changes have been done in drwlib.c, drwlib.h kbdlib.c, kbdlib.h,
  primitiv.c, comp/action.s7i, comp/gkb_act.s7i and

  tar.s7i, zip.s7i, chkstr.sd7, ide7.sd7 s7c.sd7, comp/debug.s7i and
  comp/expr_util.s7i have been altered to use the new functions
  instead of the deprecated function.
- The exception CLOSE_ERROR has been renamed to GRAPHIC_ERROR.
- The graphic drivers have been changed to raise GRAPHIC_ERROR
  instead of FILE_ERROR.
- The C macro SUPPORTS_PARTIAL_LINKING has been renamed to
  LINKER_OPT_PARTIAL_LINKING in chkccomp.c and several makefiles.
- The functions checkPartialLinking() and determinePartialLinking()
  have been added to chkccomp.c. These functions determine if
  partial linking is actually working.
- Documentation comments have been improved in keybd.s7i,
  unicode.s7i, drwlib.c and kbdlib.c.
- In several files phrases like "illegal encoding" and
  "illegal file names" have been replaced with "invalid encoding"

20220626:
- Syntax highlighting for the Nano editor has been added. Many
  thanks to Duke Normandin for creating seed7.nanorc.
- The syntax highlighting of vim (in seed7.vim) has been improved.
- The file syntaxhl.sd7 has been improved.
- Explanations about type inference, return type overloading and
  integer overflow have been improved in the FAQ.
- In the manual the tutorial chapter "For loop and containers" has
  been improved. The chapter about errors has been improved also.
- The documentation in src/read_me.txt has been improved and the
  new file src/read_me.htm has been introduced.
- The interpreter (s7) has been improved to write the error message
  with the correct line if a declaration fails (changes have been
  done in dcllib.c and error.c).
- The new library pem.s7i has been added. This library supports the
  PEM cryptographic file format.
- In encoding.s7i the function fromBase64 has been improved to
  check that no = is in the middle of a base64 string.
- The library zstd.s7i has been fixed to work correct if the ID
  field size of the dictionary is 0.
- The Seed7 compiler (s7c) has been improved to support warning
  levels.
- The compiler has been improved to support case statements if the
  C switch statement does not work for int64Type (in prc_act.s7i).
- In the compiler the string concatenation optimizations have been
  improved (in str_act.s7i).
- Tests for string concatenation have been added to chkstr.sd7.

  flt_rtl.c, flt_rtl.h and flt_act.s7i).
- In the library asn1.s7i the function printAsn1 has been improved.
- The usage of the GMP library has been disabled by default. It
  turned out that database connection libraries used GnuTLS which
  used GMP with a custom memory allocator. This caused a memory
  corruption. All makefiles now define USE_GMP as 0.
- The program chkccomp.c has been improved to:
  - Determine the C language version supported by the compiler.
  - Determine C overflow behavior of int division.
- The handling of integer division overflow has been fixed to avoid
  a MinGW gcc bug that triggers an endless loop.
- Several types in database drivers have been renamed to avoid
  violating the C++ One Definition Rule (in sql_cli.c, sql_db2.c,
  sql_fire.c, sql_ifx.c, sql_lite.c, sql_my.c, sql_oci.c,
  sql_post.c, sql_srv.c and sql_tds.c).
- Adjustments have be done in s7c.sd7 and comp/str_act.s7i to
  support compilation with a C++ compiler.
- In common.h the macro logErrorIfTrueX has been introduced.
- Function logging has been added to big_gmp.c, kbd_inf.c and
  kbd_poll.c.
- Errors in function logging have been fixed in arr_rtl.c,
  big_rtl.c, drw_x11.c and sql_rtl.c.
- Definitions of LOG1P_FUNCTION_OKAY, INT_DIV_OVERFLOW and
  INT_REM_OVERFLOW have been added to cc_conf.s7i. The definition
  of HAS_LOG1P has been removed. The file cmd_rtl.c and the program
  confval.sd7 have been adjusted.
- Documentation comments have been updated in array.s7i, bin32.s7i,
  bin64.s7i, cc_conf.s7i, external_file.s7i, file.s7i, hash.s7i,
  math.s7i and flt_rtl.c.

  Seed7 syntax highlighting.
- In the string.s7i library, the functions lower() and upper() now
  use an up to date Unicode definition.
- The library gzip.s7i has been refactored to use the new type
  gzipHeader and to avoid calling getUInt16Le().
- The function getDigestOidFromAlgorithm() has been added to the
  library x509cert.s7i.
- The pac.sd7 example program has been refactored. Now it also
  works when compiled.
- The calc7 example program has been improved to support functions
  from the draw.s7i library.
- Tests for array append ( &:= ), the 'times' operator and the
  function remove() have been added to chkarr.sd7.
- Tests in chkovf.sd7 have been refactored.
- Tests for Unicode case conversions and for conversions to UTF-8
  have been added to chkstr.sd7.
- Errors in getGidFromGroup() and getUidFromUser() have been fixed
  in the file cmd_unx.c.
- In literal.c the error message for empty char literals has been
  improved.
- The number of C compiler warnings has been reduced in sql_oci.c,
  drw_win.c and int_rtl.c.
- In drw_drv.h, drw_dos.c, drw_emc.c, drw_win.c, drw_x11.c, s7.c,
  s7c.sd7 and comp/drw_act.s7i, the graphics support has been
  changed to call drawInit() at program start.
- The function drawInit() has been added to drw_dos.c and
  drw_emc.c.
- With these changes in the graphics support, an explicit
  initialization of graphics is no longer necessary. The explicit
  graphics initialization has been removed from bmp.s7i, gif.s7i,
  ico.s7i, jpeg.s7i, png.s7i, ppm.s7i and tiff.s7i.

  DB_LOCALE.
- The compiler (s7c.sd7) has been changed to use stderr for a
  trace of functions (option: -tf).
- The compiler has been improved to support tracing of dynamic
  calls (option: -td). This tracing is also written to stderr.
- The compiler has been changed to raise ACTION_ERROR if a dynamic
  call would result in an endless recursion.
- The program chkccomp.c has been improved to restart tests if no
  numeric result could be obtained. This is necessary for the
  program to work reliable under Windows with certain virus
  detection software.
- Documentation comments have been improved in color.s7i.

20220410:
- In time.s7i, the function time(string) has been improved to
  consider the daylight saving time. Many thanks to Anders
  Carstensen for pointing out the problem and for providing a test
  program.
- Explanations of the times operator and the functions bytes(),
  bytes2Int(), bytes2BigInt(), expm1(), log1p(), ignore() and
  openServerTls() have been added to the manual.
- In the manual, the chapters about primitive actions and about the
  foreign function interface have been improved.
- The FAQ and manual have been improved to consider the Informix
  database.
- In ccittfax.s7i, the CCITT fax decoding has been improved.
- In tiff.s7i, reading of TIFF files has been improved. Now, the
  requested length of Lempel Ziv Welch compressed data is computed
  correctly.
- In jpeg.s7i, reading of JPEG files has been improved to use the

  case.
- In bitdata.s7i, the performance of the functions getBit() and
  getBits() with a msbBitStream has been improved.
- In array.s7i, the times operator has been improved to work with
  [A len L] times element.

  messages for duplicate when values.
- The program gkbd.sd7 has been improved to consider the space key.
- In ref_data.c the function refArrToList() has been improved to
  raise RANGE_ERROR for an illegal array value.
- In dcllib.c the function dcl_elements() has been improved to work
  correctly when push_stack() is a noop.
- The files sql_fire.c and sql_tds.c have been improved to reduce C
  compiler warnings.
- The program chkccomp.c has been improved to allow build tests to
  deliver a result after a delay.
- In soc_rtl.c the functions socGets() and receive_and_alloc_stri()
  have been improved to set the EOF indicator instead of raising
  FILE_ERROR if the peer has crashed.
- In soc_rtl.c, the function logError() will now be called if
  recv() fails.
- In chkccomp.c, the function determineInformixDefines has been
  improved to avoid the definition of an empty C array.
- The makefile mk_msvc.mak has been changed to define
  LIMITED_CSTRI_LITERAL_LEN. This avoids that the C compiler runs
  out of heap space.
- Documentation comments have been updated in graph.s7i, tls.s7i,
  x509cert.s7i, ar.s7i, cpio.s7i, rpm.s7i, tar.s7i and zip.s7i.

- In tls.s7i an error in processing change_cipher_spec has been
  fixed.
- The program chkbig.sd7 has been refactored to use smaller
  functions.
- An additional test for case statements has been added to
  chkprc.sd7.
- The function getPixelArray() has been added to draw.s7i.
- The function setPointerPos() has been added to graph.s7i.

  renamed to getPixmap() and getPixelData() respectively.
- The compiler (s7c) has been improved to inline the action
  DRAW_PIXEL_TO_RGB.
- The makefiles have been improved to simplify the build system. Now
  utilies like chkccomp, wrdepend, setwpath and sudo are compiled

  - It now writes more detailed error messages.
  - The function appendOption() has been improved to check if an
    option is already an element in the list.
  - The functions fileIsPresentPossiblyAfterDelay(), runTest(),
    doTestNoResultCheck(), addDynamicLibToDllListWithRpath(),

  replaced by utf16charType and utf16striType respectively. This
  avoids confusion, since sizeof(wchar_t) is 2 in Windows and 4 in
  Linux/Unix/BSD (although sizeof(wcharType) was always 2).
- Definitions of utf32charType and utf32striType have been added to
  common.h.
- Explanations of utf16charType, utf16striType, utf32charType and
  utf32striType have been added to the manual.
- In heaputl.h, the macros SIZ_WSTRI, MAX_WSTRI_LEN and ALLOC_WSTRI

  ALLOC_SQLWSTRI, UNALLOC_SQLWSTRI, stri_to_sqlwstri,
  sqlwstri_to_stri and copy_to_sqlwstri have been introduced. These
  macros allow the DB interface to work for sizeof(SQLWCHAR) == 2
  and sizeof(SQLWCHAR) == 4.
- The Informix database driver sql_ifx.c has been added.
- The macro BIGINT_LIB has been renamed to BIGINT_LIBRARY in

  ppm.s7i,
- In sql_base.s7i, the value DB_INFORMIX has been added to the
  enumeration type dbCategory.
- Functions to open Informix databases have been added to
  sql_base.s7i and sqllib.c.

- The actions DRW_IMAGE, DRW_GETIMAGE and DRW_GET have been renamed
  to DRW_GET_PIXMAP_FROM_PIXELS, DRW_GET_PIXEL_DATA and
  DRW_GET_PIXMAP respectively.
- Action and function names have been refactored to fit to each
  other. The actions DRW_CONVPOINTLIST, DRW_FPOLYLINE,
  DRW_GENPOINTLIST, DRW_GETIMAGEPIXEL, DRW_GETPIXEL, DRW_PIXELTORGB,
  DRW_POLYLINE, DRW_SETCLOSEACTION, DRW_SETCONTENT,
  DRW_SETCURSORVISIBLE, DRW_SETPOS, DRW_SETTRANSPARENTCOLOR,
  DRW_SETWINDOWNAME, DRW_TOBOTTOM and DRW_TOTOP have been renamed to

  improved. The run-time to extract a gzipped Seed7 archive with tar7
  has been reduced to 46% (measured with gcc and valgrind). Other
  usages of the inflate algorithm (PNG, ZIP, etc.) also benefit from
  the improvements.
- The compiler has been improved to:
  - Optimize overflow checks away for shift operations.

  and lzwDecompressMsbEarlyChange(string, codeSize, requestedLength).
- The files bitdata.s7i, gzip.s7i, inflate.s7i, jpeg.s7i, zstd.s7i
  and chkbitdata.sd7 have been refactored to avoid 'bitStream' as
  variable name. The name 'bitStream' is now used as interface type
  in bitdata.s7i.

  RANGE_ERROR if the string is empty.
- In big_rtl.c and big_gmp.c the functions bigFromByteBufferBe()
  and bigFromByteBufferLe() have been changed to raise RANGE_ERROR
  if the size is zero (the buffer is empty).
- The files drw_win.c, drw_x11.c, drw_drv.h, drwlib.c, drwlib.h and
  primitiv.c have been changed to support the action DRW_PFARC.

lang/seed7: fix build, add xrender dependency

    b2c0627

08:59 Pietro Cerutti (gahr) 

lang/seed7: update to 05_20211114

20211114:
- The libraries pixmap_file.s7i and graph_file.s7i have been improved
  to draw to the correct graphic window. Many thanks to Anders
  Carstensen for pointing out that text was written into the wrong
  window and for providing a test program.
- Answers to three new questions have been added to the FAQ. Answers
  to existing questions have been improved. Many thanks to Zachary
  Menzies for pointing out a problem with two dimensional arrays and
  for providing a test program.
- An unclosed <i> tag has been removed from the manual. Thanks to
  ifethereal for pointing out this error. Several other places with
  illegal HTML in doc/manual.htm have also been fixed.
- The function getXmlTagHeadOrContent() has been improved in
  scanfile.s7i and scanstri.s7i. Now, tag names start with a letter
  or underscore (_), and the function can read XML contents that
  start with the character '<' (like < <= or <> ). In this case, the
  character < is read as character reference (&lt;).
- An explanation of the exception declaration has been added to the
  manual.
- The search for the X11 Xrender extension has been improved. In
  chkccomp.c the function determineX11Defines() has been improved.
  Declarations have been moved from x11_x.h to the new file
  x11_rend.h. Adjustements have been made in drw_x11.c and fwd_x11.c.
- Two code pages for APL symbol encoding have been added to
  charsets.s7i. The graphic representation of the character '\a'
  (bell) has been changed from '\16#25cf;' to '\16#2022;' in all
  code sets.
- In the vector font cronos16 the design of the characters 'J' '£'
  and '€' have been improved.
- In the vector font cronos27 the design of the characters '£' '¤'
  and '€' have been improved.
- In analyze.c, the function analyzeProg() has been improved to work
  correctly if an error occurs.
- In itflib.c, the function itf_create() has been improved to raise
  the exception ACTION_ERROR if the source struct is NULL.
- The prototypes of the functions conWrite() and stri_to_bstriw()
  have been changed to work with constant strings.

20211009:
- Seed7's approach to avoid double library includes has been
  improved. Many thanks to Zachary Menzies for reporting the
  problem (a second library with the same name but in a different
  directory was not included) and for providing a test case to
  trigger it. The new mechanism uses the absolute path of a library
  to determine if it already has been included. Now the map of
  included libraries is not part of the compiled executable anymore.
  Changes have been made in seed7_05.s7i, analyze.c, data.h,
  infile.c, infile.h, libpath.c, libpath.h, prclib.c and prg_comp.c.
- The new library htmldom.s7i has been added. This library contains
  an improved HTML DOM parser. Many thanks to OddCitron1981 for
  suggesting to parse some of the wild HTML out there on the web. The
  functions readHtmlNode() and readHtml() have been moved from
  xmldom.s7i to htmldom.s7i. The type htmlDocument and the function
  readHtmlContainerSubNodes() have been added. Improvements of HTML
  scanning functions were also made due to this suggestion. The new
  HTML parser considers several things special for HTML:
  - Tag names and attribute names are converted to lower case.
  - There are alternate end tags for tags with optional closing tag.
  - Attributes without value get "" as value.
  - The <!DOCTYPE data is not handled as xmlNode.
  - Closing tags without opening tag are left in as is.
- The HTML scanning functions in scanfile.s7i and scanstri.s7i have
  been improved:
  - HTML tag attributes without value are allowed now.
  - Reading of HTML tag attributes now stops at the end of tag
    character (>).
  - CDATA sections are considered now.
  - The functions getXmlTagHeadOrContent(), getSymbolInXmlTag(),
    getHtmlAttributeValue() and getNextHtmlAttribute() have been
    improved.
  - The function getXmlCdataContent() has been added.
- A chapter about for-until-loops has been added to the manual.
- The makefiles and the compiler (s7c.sd7) have been improved to
  avoid linking unused system libraries (e.g. with -lm). Changes have
  been done in cc_conf.s7i, comp/action.s7i, comp/flt_act.s7i,
  comp/library.s7i, s7c.sd7, cmd_rtl.c and in the makefiles.
- The bas7.sd7 (basic interpreter) example program has been improved.
  - Now, it is possible to do a string multiplication with the *
    operator. E.g.: "ha"*3 results in "hahaha" and "ab"*2+"xy"*3
    results in "ababxyxyxy".
  - Now, the RPT$ function is checked for a negative factor.
- The wiz.sd7 example program has been refactored. The functions
  treasureNumber() and vendorDies() have been introduced.
- The bigfiles.sd7 example program has been improved to limit the
  length of the result list.
- The compiler has been improved:
  - Now, unused system libraries are not linked to the executable.
  - In comp/flt_act.s7i the implementation of FLT_DECOMPOSE has been
    improved and float comparisons set the flag mathLibraryUsed, if
    the implementation requires it.
  - Two functions named appendLibrary() have been added to s7c.sd7.
    These functions avoid that a system library is linked twice.
  - In comp/action.s7i calls of BIG_... actions now set the flag
    bigintLibraryUsed  and calls of FLT_... actions (that need the
    math system library) now set the flag mathLibraryUsed.
  - The flags bigintLibraryUsed and mathLibraryUsed have been added
    to comp/library.s7i.
- In xmldom.s7i the writeXml functions have been refactored.
  Unnecessary definitions of writeXml have been removed.
- Definitions of SYSTEM_BIGINT_LIBS and SYSTEM_MATH_LIBS have been
  added to cc_conf.s7i. The definition of ADDITIONAL_SYSTEM_LIBS
  has been removed. SYSTEM_BIGINT_LIBS and SYSTEM_MATH_LIBS are
  used in confval.sd7 and s7c.sd7.
- Several improvements in chkccomp.c have been done:
  - Now SYSTEM_MATH_LIBS and LINKER_OPT_DYN_LINK_LIBS are
    considered. This helps to avoid linking unused libraries.
  - ADDITIONAL_SYSTEM_LIBS has been renamed to SYSTEM_BIGINT_LIBS.
  - Now, it checks if fileno() succeeds after a successful
    call of popen() (this fixes a problem with Emscripten).
  - The function appendOption() has been improved.
  - The type of several indices has been changed from int to
    unsigned int (this reduces the number of C warnings).
  - The value LINKER_OPT_DYN_LINK_LIBS is now added to a
    corresponding list of system libraries if dynamic linking at
    run-time is necessary.
- In cmd_rtl.c the function doReadLink() has been improved to work
  also for symlinks in the Linux /proc filesystem (in /proc the
  stat() function reports a symlink size of 0).
- The macro environmenStrncmp has been renamed to environmentStrncmp.
- The function getProgramPath() has been moved from analyze.c to
  cmd_rtl.c. Additionally it has been improved and renamed to
  getAbsolutePath().
- In cmd_unx.c the function getExecutablePath() has been improved to
  use doReadLink() and to return a straightened absolute path (the
  special directories "." and ".." are interpreted according to
  their conventional meanings).
- The functions concatAndStraightenPath() and
  straightenAbsolutePath() have been added to str_rtl.c.
- In infile.c the functions open_infile(), close_infile(),
  open_string() and remove_prog_files() have been renamed to
  openInfile(), closeInfile(), openString() and removeProgFiles()
  respectively. Now openInfile() and openString() return a
  boolType result to indicate the success.
- In libpath.c the functions find_include_file(),
  append_to_lib_path(), init_lib_path() and free_lib_path() have
  been renamed to findIncludeFile(), appendToLibPath(),
  initLibPath() and freeLibPath() respectively. The functions
  initIncludeFileHash(), shutIncludeFileHash() and
  openIncludeFile() have been added. The added functions maintain a
  hashmap of already included files.
- In prclib.c the function prc_include() has been adjusted to call
  the new function that avoids double includes. Now the 2nd
  parameter of the action PRC_INCLUDE contains the file name to be
  included.
- In striutl.c the functions stri_to_os_utf8(), conv_to_os_stri()
  have been improved to return a boolType result that indicates
  success.
- Logging functions have been added to strlib.c.
- Documentation comments have been improved in cc_conf.s7i,
  html.s7i, osfiles.s7i, scanfile.s7i, scanstri.s7i, cmdlib.c,
  cmd_rtl.c, hshlib.c and hsh_rtl.c.

20210904:
- The linking of PostgreSQL has been improved. Many thanks go to
  SiliconWizard, for pointing out linking problems and for helping
  to investigate them. The function findPgTypeH() has been added to
  chkccomp.c. Now the search for pg_type.h and pg_type_d.h does not
  include postgres.h. In sql_post.c the include of the file
  postgres.h has been removed.
- The wiz.sd7 example program has been refactored. Now it can be
  compiled. Many thanks go to Vasiliy Tereshkov, for reporting the
  compilation problem. Additionally, several improvements of wiz.sd7
  have been done.
- The functions expm1() and log1p() have been added to the math.s7i
  library. Many thanks go to Sanjay Jain for pointing out that
  they were missing.
- In wrinum.s7i the functions str(ENGLISH, number) and
  str(GERMAN, number) have been improved to work correctly for zero.
- In forloop.s7i the definition of for-until-loops has been
  improved, such that the loop variable never gets a value outside
  of the range. The definition of for-loops has been changed to
  invoke the loop-body just at one place. Since the loop body is
  inlined, this does shorten the generated code.
- Tests for for-loops have been added to chkprc.sd7.
- The compiler (s7c.sd7) has been improved to generate better code
  for the actions BLN_TERNARY, REF_ADDR, REF_SELECT and SET_ELEM
  (changes were done in bln_act.s7i, ref_act.s7i and set_act.s7i).
- The compiler has been improved (in comp/enu_act.s7i), to check
  for a possible RANGE_ERROR, if an integer is converted to an
  enumeration value (action ENU_ICONV2).
- The compiler has been improved to optimize expressions like
  ord(aBigExpression mod aPowerOfTwo).
- The function chkBigOrdWithBigMod has been added to chkbig.sd7.
  This function checks the optimizations done with expressions like
  ord(aBigExpression mod aPowerOfTwo).
- Tests for the ternary operator have been added to chkstr.sd7.
- Tests for the 'element in bitset' operator have been added to
  chkset.sd7. These tests check the compiler optimizations for
  SET_ELEM.
- Definitions of HAS_EXPM1 and HAS_LOG1P have been added to
  cc_conf.s7i.

  find_include_file() (in libpath.c) have been adjusted to fail if
  they are called at runtime.
- In drw_win.c the function drwCapture() has been improved to release
  the screen device context. This avoids a resource leak.
  Additionally, the stretch blt mode is now set with
  SetStretchBltMode().
- The program chkccomp.c has been improved to consider the X11
  extension Xrender. Now definitions of HAS_XRENDER_EXTENSION and

  thanks go to Moosa Yahyazadeh for providing a bugs report for
  seed7-pkcs1. The following improvements have been done:
  - In pkcs1.s7i the function emsaPkcs1V15Decoding has been improved
    to check that every padding byte is actually 16#ff and that at
    least 8 padding bytes are present. (Point 1 of report)
  - In pkcs1.s7i the functions rsaEncryptBytes() and rsaDecryptBytes()
    have been removed and usages of them have been replaced with
    rsassaPkcs1V15Encrypt() respectively rsassaPkcs1V15Decrypt().
    (Point 2 of report)
  - In x509cert.s7i the function validateSignature() has been improved
    to compare the digest algorithm obtained from the certificate with
    the digest algorithm stored in the ASN.1 digestAlgorithmIdentifier
    of the decrypted signature. (Point 3 of report)
  - The functions getRsaSignature() and getEcdsaSignature() have been
    added to x509cert.s7i. These functions check that the encoded
    message has not any trailing garbage bytes. (Point 4 of report)
- The functions getDigestAlgorithm(), showSignatureAlgorithm() and
  getDigestFromSignatureAlgorithm() have been added to x509cert.s7i.
- In x509cert.s7i the function validateSignature() has been improved

- Several optimizations have been done in the compiler (s7c.sd7):
  - In comp/prc_act.s7i the function process_prc_for() has been
    improved to store the range of the for-variable if the start or
    the end value is constant (or both are constant).
  - In comp/intrange.s7i the function getIntRange() has been improved
    to get a range for the action INT_MULT and for a for-variable (if
    the start or the end value of the for-loop is constant).
    Determining the maximum of INT_LSHIFT has been improved.
  - In comp/drw_act.s7i the function drwRgbColor() is now defined as
    macro, if the optimization level requires it (-oc3).
  - In comp/arr_act.s7i in the function process_const_arr_idx() the
    index check has been omitted, if it is known that the index is
    always in the range of the constant array.
  - In comp/int_act.s7i the actions INT_MULT and INT_MULT_ASSIGN have
    been improved to use the builtin mult overflow function, if
    available. The improvements were made in the functions

  - The new function varChangedInStatements() has been added to
    comp/prc_act.s7i.
  - Code has been moved from process_prc_for() in comp/prc_act.s7i
    to the new function defineForStartVariable in comp/expr_utl.s7i.
  - In s7c.sd7 the initialisation of local arrays has been improved
    to recognize if all elements of the array are the same. In
    this case arrTimes(), arrMalloc(), malloc() or memset() are
    used instead of copying an array. The functions canUseArrTimes()
    and assignArrayValue() have been added, and the function
    identical_values() has been moved.
- Tests for the operator &:= (append one element to an array) have
  been added to chkarr.sd7.

lang/seed7: update to 05_20210322

Changes:

20210322:
- Some missleading tests have been removed from chkflt.sd7. Many
  thanks go to Zachary Menzies for pointing out problems with the
  tests for trunc() and round().
- The new library gif.s7i has been added. This library supports the
  GIF image file format.
- The new library bmp.s7i has been added. This library supports the
  BMP image file format. The functions readBmp() and str(BMP) have
  been moved from draw.s7i to the new library bmp.s7i. The performance
  and functionality of readBmp() has been improved. The deprecated
  function read_bmp() has been removed (the function readBmp() can be
  used instead).
- In bitdata.s7i the performance of getBitsLsb() and getBitsMsb() has
  been improved.
- The functions peekBitsLsb(), skipBitsLsb(), peekBitsMsb() and
  skipBitsMsb() have been added to bitdata.s7i.

- Tests for peekBitsLsb() and peekBitsMsb() have been added to
  chkbitdata.sd7.

  chkstr.sd7.
- The function getStriUpToChar() has been added to bytedata.s7i.
- The experimental function seekable() has been added to file.s7i,
  null_file.s7i, clib_file.s7i, external_file.s7i, strifile.s7i,
  subfile.s7i, utf16.s7i, iobuffer.s7i, gzip.s7i, lzma.s7i, xz.s7i and
  zstd.s7i.
- Several optimizations have been done in the compiler (s7c.sd7):
  - In comp/arr_act.s7i the index check for the action ARR_IDX has
    been improved.
  - In comp/int_act.s7i the overflow check for the actions
    INT_ADD_ASSIGN and INT_SBTR_ASSIGN has been improved.
  - In comp/intrange.s7i the function getIntRange() has been improved
    to get a range for the action INT_LSHIFT and to get a better range
    for the action INT_MOD.
  - In comp/str_act.s7i the function optimize_str_cat has been
    improved to generate a call of strConcatChar() or
    strConcatCharTemp(), if applicable.
  - In comp/chr_act.s7i the generation of the macro chrStrMacro()
    has been improved to avoid #line directives in macro parameters.
- In drw_win.c the performance of the function drwImage() has been
  improved. Instead of calling SetPixel() for every pixel it now does

- The function determineLseekFunction() has been added to chkccomp.c.

20210223:
- Spelling corrections have been done in several files. Many thanks go
  to Jens Schleusener, for sending a source code misspelling report
  from Fossies.
- The new library png.s7i has been added. This library supports the
  PNG image file format.
- Seed7 has been improved to compile under Android with termux. This
  is described in src/read_me.txt.
- A chapter about Unicode characters has been added to the manual.
- The make7.sd7 example program has been improved. The processing of
  makefiles in make.s7i has been improved to process every rule just
  once. The handling of the option -n (don't execute commands) has
  been improved to work in the same way as in other make tools.
- The test program chkbin.sd7 has been improved to to allow two
  possible NaN values as result of 0.0 / 0.0.
- The test program chkflt.sd7 has been improved to allow that for some
  test cases trunc() and round() either return the correct value
  (integer.last) or raise RANGE_ERROR.
- Tests for array bitset have been added to chkarr.sd7.
- Tests for conversion and cardinality have been added to chkset.sd7.
- The functions XChangeProperty() and XMapWindow() have been added to
  fwd_x11.c and x11_x.h.
- The makefile mk_clang.mak has been improved to allow the replacement
  of system headers (x11_x.h and fwd_term.h). This way compilation
  works also without the original headers.
- The warning box created by warn.c had too much width to be readable
  in termux. So this width has been reduced.
- In drw_win.c the functions drwXPos() and drwYPos() have been fixed
  to return coordinates relative to the parent window.
- The checks for the C compiler option -ftrapv in chkccomp.c have
  been improved. Now it is recognized, if integer overflow raises the
  signal SIGTRAP. Clang at the ARM processor uses SIGTRAP.
- Changes have been done in sigutl.c to handle SIGTRAP and to raise
  OVERFLOW_ERROR in the signal handler (if chkccomp.c has recognized
  that an integer overflow raises SIGTRAP).
- Changes have been done in chkccomp.c to support PostgreSQL version
  13. Additionally the logic to search for PostgreSQL dlls has been
  improved. Now it searches also for the libraries libcrypto and
  libssl. Now POSTGRESQL_DLL can be specified, with an absolute path
  of libpq.dll, in the makefile (which should echo it to chkccomp.h).
- In the compiler (s7c.sd7) the handling of actual parameters for
  formal inout parameters has been improved. Now a struct element can
  be used as actual parameter for a formal inout parameter.
- The compiler has been improved to reduce range checks for the
  expressions char(number), chr(number) and card(bitset(number)).
- Interpreter and compiler have been improved to support the action
  REF_ISTEMP. The function isTemp() has been added to progs.s7i.
- In comp/intrange.s7i the function getIntRange() has been improved
  to determine result ranges for INT_ADD and integer constants.
- The compiler has been improved to assure that sigsetjmp() is not
  called with a value other than 0 or 1 for the second parameter
  (savesigs). According to the specification of sigsetjmp() all
  integer values are allowed for the second parameter (savesigs)
  and a non-zero value triggers a save of the current signal mask.
  ARM / Android / termux decided that just 0 and 1 are valid values
  and that any other value triggers a termination of the program
  (with SIGABRT).
- The function drwCapture() in drw_win.c has been improved to work
  correct, if the screen has been scaled.
- In drw_win.c the functions drwPut() and drwSetTransparentColor()
  have been improved such that images with a transparent color work.
- The runtime of drwRgbColor() in drw_x11.c has been reduced by 31%
  (measured with gcc and valgrind, when reading a PNG image). This
  takes effect if a true color display is used.
- The runtime of drwRtlImage in drw_rtl.c has been reduced by 63%
  (measured with gcc and valgrind, when reading a PNG image). The
  function memcpy_pixel() uses loop unrolling inspired by Duff's
  device.
- The program chkccomp.c has been improved to determing the macro
  rgbToPixel() (if X11 graphics is used).
- In exec.c the function exec_expr() has been improved to clear
  the TEMP flag for all results.
- The makefiles have been improved to write the name of the make
  utility and the name of the makefile to version.h.

20210130:
- The parser (used by interpreter and compiler to read a program) has
  been improved to work correct, if seed7_05.s7i is not included.
  Many thanks go to Domingo Alvarez Duarte for pointing out that a
  missing seed7_05.s7i include statement causes a parser error.
- The example program mirror.sd7 has been added. This program mirrors
  a rectangular screen area in a window.
- The function capturePixmap has been added to graph.s7i. This
  function can be used to capture rectangular areas from the screen.
- In the library graph.s7i the function openSubWindow() has been
  improved to allow top level windows without window decorations.
  This can be done by using the empty window as parent window.
- Chapters about pragmas and compilation errors have been added to the
  manual.
- The parser has been improved to work reliable in out of memory
  situations. Now the fatal parser error "Out of heap space" does not
  terminate the program.
- The minor versions of interpreter and compiler have been increased.
  Now interpreter and compiler share the same revision level. Every
  compilation of the Seed7 interpreter increases the revision level.
- A definition of VERSION_REVISION_LEVEL has been added to
  cc_conf.s7i. This is used in confval.sd7 and s7c.sd7.
- Interpreter and compiler have been improved to support the new
  action DRW_CAPTURE.
- In analyze.c the function analyzeProg() has been improved to
  catch the "Out of heap space" error and to clean up memory in out
  of memory situations. Now the old values of the global variables
  prog, interpreter_exception curr_exec_object, curr_argument_list and
  trace are restored, when the function is left.
- In analyze.c the functions analyzeFile() and analyzeString() have
  been improved to work without setting interpreter_exception. Now
  these functions work the same in interpreted and compiled programs.
- In atom.c the function read_atom() has been improved to keep the
  data structure consistent in out of memory situations.
- The functions pop_owner() and close_current_stack() have been added
  to name.c.
- In name.c the functions free_params(), get_object() and push_name()
  have been improved to have an additional 'currentProg' parameter.
- In name.c the function get_object() has been improved to reverse its
  changes in case of an error.
- In name.c the handling of errors has been improved in push_name(),
  eval_name_list(), inst_list(), inst_object_expr(), find_name(),
  search_name(), dollar_parameter() and dollar_inst_list(). In error
  situations changes are reversed, memory is freed and stack growing
  and shrinking is now done in a consistent way.
- In entutl.c the function copy_params() has been improved to allocate
  the parameters first in a list and to assign them later.
- The new functions pop_name_list() and get_entity_node() have been
  added to entutl.c.
- In entutl.c the function get_entity() has been improved to handle
  error situations (out of memory).
- In entutl.c in the function init_entity() dereferencing NULL is
  avoided now, if the memory allocation fails.
- In blnlib.c the function bln_ternary() has been improved to work
  correct, if evaluate() returns NULL. This happens if an exception
  is triggered inside evaluate().
- Implementations of drwBorder() and drwSetPos() have been added to
  drw_emc.c. The functions drwXPos() and drwYPos() have been improved.
- The function drwCapture() has been added to drw_x11.c and drw_win.c.
- The function drwOpenSubWindow() has been improved in drw_x11.c and
  drw_win.c to support the creation of unmanaged top level windows
  without window decorations (if the parent window is empty).
- The function omitWindowDecorationsAndTaskbarEntry() has been added
  to drw_x11.c.
- In flt_rtl.c the function setMantissaAndExponent has been improved
  to work without division by DOUBLE_MANTISSA_FACTOR.
- The program chkccomp.c has been improved to write an error message,
  if executing a test program fails.
- In error.c the functions read_ustri8_line(), read_and_print_line()
  and ustri8_buffer_to_stri() have been improved to work reliable in
  out of memory situations.
- In fatal.c the function no_memory() has been improved to do a long
  jump to analyzeProg().
- In listutl.c the function append_element_to_list() has been improved
  to keep the list_insert_place unchanged in out of memory situations.
- In sctlib.c in the function sct_cat() the code to handle an error
  has been improved, to avoid using a pointer that might be invalid
  because of a previous realloc(). The function sct_elem() has been
  improved to consider that grow_stack() might fail.
- In typeutl.c the function get_varfunc_type() has been improved to
  work correct, if new_type() returns NULL. This can happen in out of
  memory situations.
- In findid.c the functions clean_idents() and write_idents() have
  been refactored to use a progType parameter and to allow NULL
  values in the ident tables.
- In flistutl.c the function heap_chunk() has been improved to never
  do a realloc() on a memory chunk and to explain why this is done.
- In flistutl.h the macros HEAP_OBJ(), HEAP_L_E(), HEAP_NODE() and
  HEAP_FILE() have been fixed to return FALSE in out of memory
  situations.
- In hshlib.c the macro isit_not_null() has been added to several
  functions to assert that function references and compare results are
  not NULL.
- In prclib.c the functions prc_begin(), prc_local(), prc_res_begin(),
  prc_res_local(), prc_return(), prc_return2(), prc_varfunc() and
  prc_varfunc2() have been improved to handle error situations (out of
  memory).
- In prclib.c the macro isit_not_null() has been added to prc_case(),
  prc_case_def(), prc_case_hashset() and prc_case_hashset_def(). This
  macro checks that the sets after the keyword 'when' are not NULL.
- In identutl.c the function init_idents() has been changed to leave
  a failed initialisation as is (this is cleaned up later).
- In prg_comp.c the function prgDestr() has been improved to allow
  NULL for elements of the program structure. The function interpret()
  has been improved to restore the global variable
  interpreter_exception.
- In exec.c the functions getErrInfoFromFailValue() and do_exec_call()
  have been added. The function exec_expr() has been improved to
  restore the global variable interpreter_exception.
- In executl.c the functions do_destroy(), create_return_object(),
  create_local_object(), destroy_local_object() and
  destroy_local_init_value() have been improved to handle error
  situations (out of memory).
- In match.c the function match_subexpr() has been improved to
  handle out of memory situations.
- In runerr.c the functions write_position_info() and
  write_call_stack_element() have been improved to recognize valid
  data better.
- In runerr.c the functions run_error(), empty_value() and
  var_required() have been improved to write the error message only,
  if exception tracing is switched on. Now these functions raise
  ACTION_ERROR instead of RANGE_ERROR.
- The function freeOptions() has been added to s7.c. The function
  raise_error2() has been improved to handle an out of memory
  situation.
- In symbol.c the function close_symbol() has been improved to allow
  NULL for symbol.name and symbol.striValue.
- In syvarutl.c the function init_sysvar() has been improved to
  define a dummy value for SYS_EXPR_TYPE (EXPR_TYPE). This avoids an
  error, if the source has no include directive.
- The function printLocObj() has been added to traceutl.c. The
  functions prot_list_limited() and trace1() have been improved to
  recognize corrupt category fields.
- In cmd_rtl.c code has been moved from cmdReadlink(), cmdFileTypeSL()
  and cmdGetcwd() to the new functions doReadLink(), getFileTypeSL()
  and doGetCwd() respectively. The new functions use err_info to
  report errors instead of raising an exception. The old functions
  have been refactored to call the new functions.
- In cmd_rtl.c the function followLink() has been refactored to call
  getFileTypeSL() and doReadLink().
- The program levelup.c has been added. This program is called by the
  makefile to increase the revision level of interpreter and compiler.
- In comp/expr_utl.s7i the function prepare_win_result() has been
  fixed to use drwDestr() instead of winDestr().
- The system declaration for "type" hase been removed from syntax.s7i.
- The makefiles have been adjusted to increase the revision level
  (stored in level.h) before the interpreter is compiled. This way
  interpreter and compiler get the same revision level.
- Documentation comments have been improved in array.s7i, graph.s7i,
  leb128.s7i, analyze.c, cmd_rtl.c, drw_emc.c, drw_win.c, drw_x11.c,
  entutl.c, error.c and exec.c.

lang/seed7: update to 05_20210106

Changelog:
- The declaration of in-parameters has been changed to work the same
  way as all other parameter declarations (val-, ref-, inout-, attr-
  and in-var-parameters). Many thanks go to Zachary Menzies for
  pointing out a problem with in-parameters and for providing a test
  program. The new in-parameters fix this problem.
- The support for function types (func aType and proc) in interpreter
  and compiler has been improved.
- The support for Emscripten (a C compiler that generates JavaScript
  and WebAssembly) has been improved. The support of Emscripten is
  experimental (see also src/read_me.txt).
- The library http_response.s7i has been improved to set the correct
  content-type for more file types (css, javascript, wasm, gif, bmp,
  pdf). This way the comanche webserver also works better.
- The function getCgiParameters() in cgi.s7i has been improved to
  accept also elements wihout equals sign (in this case value is
  assumed to be "").
- The function readPropertyFile8() has been added to the library
  propertyfile.s7i. This function processes an UTF-8 encoded property
  file.
- In propertyfile.s7i the function readPropertyNameOrValue() has been
  changed to work correct for unicode escapes (\u) and for escaped
  newlines. An extended unicode escape (\U) has been added also.
- Testcases that check if seek() does clear the EOF flag have been
  added to chkfil.sd7.
- The Seed7 parser (used by interpreter and compiler) has been
  improved, to recognize if the same syntax is declared twice. In this
  case a compile-time error is written.
- The FAQ has been improved to explain the simple profiling of the
  Seed7 compiler.
- The simple profiling of the compiler has been improved to recognize,
  if a function has been left without taking profiling into account.
- The compiler has been improved to recognize if a raise statement
  leaves a function and generates code to make the profiling work
  correct (if it has been enabled).
- The recognition of constant expressions in the compiler has been
  improved to consider variable functions as variable. The changes
  are in comp/const.s7i in two functions named isConstantCall().
- Changes have been done in seed7_05.s7i and integer.s7i such that the
  new in-parameters work as expected.
- The interpreter has been improved to support the actions DCL_IN1,
  DCL_IN2, TYP_SET_IN_PARAM_REF and TYP_SET_IN_PARAM_VALUE.
- The functions dcl_in1() and dcl_in2() have been added to dcllib.c.
- The functions typ_set_in_param_ref() and typ_set_in_param_value()
  have been added to typlib.c.
- Changes in syntax.c and token.c make sure that the new error
  SYNTAX_DECLARED_TWICE is recognized.
- In prclib.c the function prc_cpy() has been improved to take into
  account that MATCHOBJECT is constant (and the underlaying object
  is variable).
- In cmd_unx.c the function setenv7() has been improved to work
  correct, if a value is enlarged.
- In cmd_unx.c the functions getenv7(), setenv7() and unsetenv7() have
  been improved to optionally work case insensitive.
- Changes in cmd_drv.h, cmd_rtl.c and fil_unx.c allow that some
  operating system properties are determined at run-time. This is used
  for Emscripten.
- The functions setenvForNodeJs() and unsetenvForNodeJs() have been
  added to cmd_unx.c. Now setenv() and unsetenv() have also an effect
  on the environment used by Node.
- The file drw_emc.c has been added. This file provides graphic access
  using browser capabilities. It is used if Seed7 is compiled with
  emcc.
- The file pre_js.js has been added. This JavaScript code is included
  by Emscripten. It sets up program path and arguments, if the program
  runs in the browser.
- In cmd_rtl.c the function systemForNodeJs() has been improved to
  return -1, if the command cannot be executed.
- The makefiles mk_emccl.mak and mk_emccw.mak have been improved to
  store the environment variables in seed7/bin/emcc_env.ini. The macro
  CC_ENVIRONMENT_INI, which defines the path of seed7/bin/emcc_env.ini,
  is now written to version.h. This way the Seed7 compiler can be used
  without setting up Emscripten.
- Changes have been done in error.c and error.h to introduce the new
  errors SYNTAX_DECLARED_TWICE and KIND_OF_IN_PARAM_UNDEFINED. The
  error UNEXPECTED_SYMBOL has been replaced with EXPECTED_SYMBO.
- The functions increaseLevelOfCatchedExceptions() and
  decreaseLevelOfCatchedExceptions() have been added to comp/error.s7i.
  These functions are used in comp/prc_act.s7i.
- In comp/expr.s7i the function declare_type_if_necessary() has been
  improved to take a existing typeCategory of BLOCKOBJECT into account.
- In comp/type.s7i the function getExprResultType() has been improved
  to check that the category is a CALLOBJECT.
- Definitions of LINKER_OPT_SPECIAL_LIB and SPECIAL_LIB have been added
  to cc_conf.s7i.
- The files s7c.sd7, confval.sd7, cmd_rtl.c, mk_emccl.mak and
  mk_emccw.mak have been improved to use the new configuration values.
- The parameter list of the functions cmdSetGroup() and cmdSetOwner()
  has been changed in comp/cmd_act.s7i, cmd_drv.h, cmd_unx.c and
  cmd_win.c. Now group and owner are constant strings.
- Documentation comments have been added or improved in cc_conf.s7i,
  cgi.s7i, csv.s7i, propertyfile.s7i and graph.s7i.

lang/seed7: update to 05_20200531

20200531:
- The libraries tar.s7i, cpio.s7i and rpm.s7i have been improved such
  that the file system functions follow symbolic links (inside of the
  archive).
- The library zip.s7i has been improved to support the functions
  setFileMode(), setMTime() and putFile().
- The library ar.s7i has been improved to allow UTF-8 file names and to
  support the functions setFileMode(), setMTime(), putFile() and
  removeFile().
- The library rpm.s7i has been improved to support a LZMA compressed
  payload.
- The library cpio.s7i has been improved such that setFileMode(),
  putFile() and mkdir() work correct.
- The library lzma.s7i has been fixed such that xz.s7i can handle
  uncompressed chunks in an XZ archive. A bug in the function length()
  has been fixed also.
- The new library fileutil.s7i has been added. This library supports
  inserting and deleting areas in a file. The function copyFile, which
  copies data between open files, has been moved from file.s7i to
  fileutil.s7i.
- The function truncate(), which changes the length of a file, has been
  added to file.s7i, external_file.s7i, clib_file.s7i, strifile.s7i and
  utf16.s7i.
- The library iobuffer.s7i has been improved to allow switching between
  reading and writing (and vice versa) as long as seek() is called in
  between. The functions flush() and close() have been added and the
  functions seek(), tell() and moveLeft() have been improved.
- The function deflate(), which deflates a string has been added to the
  library deflate.s7i.
- The function moveLeft() has been improved in strifile.s7i and
  stritext.s7i.
- The function timestamp1601 has been added to time.s7i.
- The bas7.sd7 (basic interpreter) example program has been improved.
  Support for LINPUT statements, for the function RPT$ and for the
  string concatenation operator & has been added. The predefined
  subprogram CHAR has been improved. Now PRINT statemens allow a colon
  (:) between strings to describe a line break. Now INPUT statements
  allow a colon (:) between input prompt and variable list. A dummy
  implementation of the predefined subprogram SOUND has been defined.
- In seed7_05.s7i the definition of ::= for the type void has been
  changed to use the action ENU_CREATE instead of PRC_NOOP. This avoids
  a strange interpreter message (loc not dumped) if a void value is
  written.
- Tests in chkint.sd7 have been split into several functions.
- Documentation in the FAQ, the manual and s7c.1 has been improved.
- Interpreter and compiler have been improved to support the new action
  FIL_TRUNCATE.
- The compiler has been improved (in comp/inline.s7i in the function
  push_inline_func_param) to add a "const" for a parameter definition.
  This avoids a compilation error with g++.

lang/seed7: update to 05_20200502

20200502:
- As suggested by Zachary Menzies a detection of more modifier keys has
  been added. E.g.: KEY_SHIFT_LOCK and KEY_NUM_LOCK. These modifier
  keys have a state. The state of KEY_SHIFT_LOCK can be retrieved with
  buttonPressed(KEYBOARD, KEY_SHIFT_LOCK_ON).
- Several new keys and key combinations such as KEY_PRINT, KEY_PAUSE,
  KEY_ALT_LEFT and KEY_SFT_MENU have been added to keybd.s7i. Existing
  definitions in keybd.s7i have been refactored. Key names in
  keydescr.s7i have been updated.
- The program gkbd.sd7 has been improved to show the new capabilies of
  the keybord interface.
- The bas7.sd7 (basic interpreter) example program has been improved.
  Support for the predefined subprograms CHAR, CLEAR, COLOR, HCHAR,
  KEY, SCREEN and VCHAR and for the function SEG$ has been added.
- The bitmap font font8x8 has been added. This is a font with 8x8 pixel
  used by the TI-99/4A homecomputer.
- The functions line() and column() have been added to pixmap_file.s7i.
- The function replace1() has been added to string.s7i.
- In the manual the chapters about types and the keyboard have been
  improved.
- The compiler has been improved to link database libraries only if
  they are needed.
- The compiler has been improved to use builtin functions of the C
  compiler (if available) to do integer overflow checks. This reduces
  the runtime of the xz (lzma2) decompression by 4% (measured with gcc
  and valgrind, when decompressing a binary Seed7 package).
- The compiler has been improved to use a better approach to test for
  integer overflow of addition and subtraction, if no builtin functions
  are available. This reduces the runtime of the xz (lzma2)
  decompression by 0.8% (measured with gcc and valgrind, when
  decompressing a binary Seed7 package).
- The compiler has been improved to optionally suppress the generation
  of checks for integer division by zero with the option -sd.
- The simple function profiling of the Seed7 compiler has been improved
  to write the place and the name of the Seed7 function and to avoid
  a C compiler error about "too many initializers".
- The compiler has been improved to write a warning if there is a catch
  statement for an exception although the checks for this exception
  have been suppressed (with the option -s).
- The compiler has been improved to work correct for all corner cases
  of the string operations [, mult and @:=.
- Testcases for the operators [, mult and @:= and for the functions
  pos() and rpos() have been added to chkstr.sd7.
- Testcases for the exception RANGE_ERROR have been added to
  chkbig.sd7. The function bigInteger() and the operators radix, RADIX
  and parse are checked now, if they correctly raise RANGE_ERROR.
- Testcases for the exception RANGE_ERROR have been added to
  chkint.sd7. The functions bytes() and integer() and the operators
  radix, RADIX, sci and parse are checked now, if they correctly raise
  RANGE_ERROR.
- Testcases for the exception NUMERIC_ERROR have been added to
  chkint.sd7. The operators div, rem, mdiv, mod and ** are checked
  now, if they correctly raise NUMERIC_ERROR.
- A lot of testcases has been added to chkint.sd7 and chkovf.sd7 in
  the function check_reduced_overflow_checking_for_sums().
- In comp/big_act.s7i the function process_const_big_ipow has been
  improved to allow that the check for a negative exponent can be
  optionally omitted.
- In chkovf.sd7 the checks for the operators rem and mod have been
  improved to allow that the operators return the correct result
  instead of raising OVERFLOW_ERROR.
- Index access in comp/str_act.s7i and comp/bst_act.s7i has been
  improved to work also for the index integer.first (now the index is
  casted to (unsigned) and afterwards 1 is subtracted).
- In comp/intrange.s7i the function getIntRange has been improved to
  return better ranges for INT_ABS and INT_NEGATE.
- The keyboard driver gkb_x11.c has been improved to support new keys
  and key combinations. Additionally the modifier state is synched now
  with the keypresses. This allows reading a modifier key state (e.g.
  (control has been pressed) from the moment when the main key (e.g.
  the letter A) was pressed.
- The program chkccomp.c has been improved to determine the values
  CHECK_INT_DIV_ZERO_BY_ZERO, HAS_BUILTIN_OVERFLOW_OPERATIONS and
  SYSTEM_DATABASE_LIBS. The logic to determine the values
  CHECK_INT_DIV_BY_ZERO, CHECK_INT_REM_BY_ZERO and
  CHECK_INT_REM_ZERO_BY_ZERO has been improved.
- The configuration value CHECK_INT_DIV_ZERO_BY_ZERO,
  BUILTIN_ADD_OVERFLOW, BUILTIN_SUB_OVERFLOW, BUILTIN_MULT_OVERFLOW
  and SYSTEM_DATABASE_LIBS have been added to cc_conf.s7i, confval.sd7
  and cmd_rtl.c.
- Documentation comments have been added or improved in cc_conf.s7i,
  encoding.s7i, gzip.s7i, lzma.s7i, pixmap_file.s7i, scanfile.s7i,
  sql_base.s7i, string.s7i, xz.s7i, sigutl.c and striutl.c.

20200405:
- The new library xz.s7i has been added. This library supports XZ
  compressed files.
- The new library lzma.s7i has been added. This library supports LZMA
  compressed files.
- The library rpm.s7i has been improved to support an XZ compressed
  payload.
- The library tar_cmds.s7i and the program tar7.s7i have been improved
  to support XZ and LZMA compressed tar archives.
- The library zip.s7i has been improved to support Unicode file names.
- As suggested by Zachary Menzies a detection of modifier keys has been
  added. E.g. buttonPressed(KEYBOARD, KEY_SHIFT). Additionally several
  new key combinations such as KEY_SFT_MOUSE1 and KEY_CTL_PAD_CENTER
  have been added to keybd.s7i.
- The program gkbd.sd7 has been improved to show the new capabilies of
  the keybord interface.
- Interpreter and compiler have been improved, to write a compile time
  error, if a numerical escape sequence in a string or char literal
  is too big.
- The compiler has been improved to omit overflow checks for the
  dividend of the mod operator, if the divisor is a power of two. This
  reduces the runtime of the xz (lzma2) decompression by 2.3% (measured
  with gcc and valgrind, when decompressing a binary Seed7 package).
- The compiler file comp/intrange.s7i has been added. This file defines
  the function getIntRange(), which computes the range of possible
  results for several operators (e.g.: div, rem, mdiv, mod, >>) and
  functions (e.g.: sqrt, length, pos, rand, log).
- The compiler has been improved to use the function getIntRange() to
  omit overflow checks for addition, subtraction, multiplication and
  left shift of integer values. This reduces the runtime of the xz
  (lzma2) decompression by 0.4% (measured with gcc and valgrind, when
  decompressing a binary Seed7 package).
- In the compiler the code generation for the operators div, rem, mdiv,
  mod, * and << has been improved to work without catching the
  exception OVERFLOW_ERROR.
- The compiler has been improved to allow that a range check is
  suppressed with -sr for the action FLT_BITS2SINGLE (convert integer
  to single precision float value).
- The compiler has been improved to generate code that writes the error
  message of a DATABASE_ERROR, if the exception is uncatched.
- The compiler has been improved to suppress the usage of the C
  compiler option CC_OPT_TRAP_OVERFLOW (-ftrapv), if the Seed7 compiler
  option -so (suppress overflow checks) is used.
- The makefiles mk_clang.mak, mk_clangw.mak and mk_osxcl.mak have been
  improved to define CC_OPT_TRAP_OVERFLOW with the value -ftrapv.
- The functions check_mod_by_power_of_two_optimization() and
  check_mod_by_computed_power_of_two_optimization() have been added
  to chkint.sd7. This functions check the mod operator regarding
  the new compiler optimization for the mod dividend.
- The functions check_reduced_overflow_checking_for_sums(),
  check_reduced_overflow_checking_for_mult() and
  check_reduced_overflow_checking_for_lshift() have been added to
  chkint.sd7 and chkovf.sd7. This functions test the compiler
  optimization to reduce overflow checking with getIntRange().
- The libraries aes.s7i, bitdata.s7i, color.s7i, deflate.s7i, draw.s7i,
  ico.s7i, msgdigest.s7i, pkcs1.s7i, showtls.s7i and utf16.s7i have
  been improved to use the division operators 'mdiv' and 'mod' instead
  of 'div' and 'rem'.
- The configuration value CC_OPT_TRAP_OVERFLOW has been introduced in
  cc_conf.s7i, confval.sd7, s7c.sd7, chkccomp.c, cmd_rtl.c and
  read_me.txt.
- The function write_exception_info() has been added to runerr.c. This
  function is called in executl.c.
- The keyboard drivers gkb_win.c and gkb_x11.c have been improved to
  support modifier keys and more key combinations.
- Definitions for 31 new key compinations and 9 modifier keys have
  been added to keybd.s7i and keydescr.s7i.
- Documentation comments have been improved in ar.s7i, cc_conf.s7i
  and csv.s7i.

  the actions FLT_TRUNC and FLT_ROUND do the correct check for the
  exception RANGE_ERROR.
- The database driver sql_oci.c has been improved to support the types
  BINARY_FLOAT and BINARY_DOUBLE.
- Tests for FLOAT and DOUBLE fields have been added to chkdb.sd7.
- A definition of the constant GZIP_MAGIC has been added to gzip.s7i.
- In file.s7i and iobuffer.s7i the functions hasNext() and length()
  have been changed to use an inout parameter for the file. This fixes
  a problem in compiled programs with some file systems where also an
  inout parameter is used for the file.
- The file db_oci.h has been improved to define SQLT_BFLOAT,
  SQLT_IBFLOAT, SQLT_BDOUBLE and SQLT_IBDOUBLE.
- In fltlib.c the functions flt_trunc() and flt_round() have been
  improved to do the correct check for the exception RANGE_ERROR.

20200209:
- The new database driver sql_tds.c has been added. This driver uses
  the Tabular Data Stream (TDS) protocol to transfer data between
  database server and client. TDS is used by SQL Server and Sybase.
  This driver allows the connection to a SQL Server database from
  Linux.
- The new library db_prop.s7i has been added. This library provides a
  collection of database properties.
- The example program chkdb.sd7 has been improved:
  - Tests with comments in sql statements have been added.
  - Tests that fetch boolean values from numeric fields have been
    added.
  - Tests for date, time, datetime and timestamp fields have been
    added.

  accept more variants of the ISO 8601 time and date format including
  variants with a time zone.
- The interpreter (s7) has been improved to write the error message of
  a DATABASE_ERROR, if the exception is not catched.
- In tim_rtl.c the function timUtcFromTimestamp() has been improved to
  work without calling gmtime() or gmtime_r() or gmtime_s(). Now the
  function always works with a 64-bit signed timestamp. Gmtime() uses
  time_t, which can be 32-bit or 64-bit and it can be signed or
  unsigned.
- In tim_rtl.c the function timToTimestamp() has been improved to work
  without calling mkutc(). This way the function always works with a
  64-bit signed timestamp. Mkutc() is also defined in tim_rtl.c and it
  uses the system dependend type time_t.
- In tim_rtl.c the functions timToOsTimestamp(), assignTime() and
  dateFromDaysSince1900() have been added and the functions
  timFromBigTimestamp() and timToBigTimestamp() have been removed.

  optionally ignore exceptions.
- The functions leaveExceptionHandling(), saveFailState() and
  restoreFailState() have been added to runerr.c. This function is used
  in executl.c and prclib.c.
- In numutl.c the functions getDecimalBigRational() and
  getDecimalFloat() have been improved to accept both, a decimal point
  and a decimal comma.
- In several database drivers the function processStatementStri() has
  been improved to replace a comment with a space.
- Interpreter and compiler have been improved to support the actions
  SQL_ROLLBACK, SQL_GET_AUTO_COMMIT and SQL_SET_AUTO_COMMIT.
- The functions sqlRollback(), sqlGetAutoCommit() and
  sqlSetAutoCommit() have been added to sql_cli.c, sql_lite.c,
  sql_my.c, sql_oci.c, sql_post.c and sql_rtl.c.
- In the database driver sql_lite.c the functions sqlBindTime() and
  sqlColumnTime() have been improved to support more time and date
  formats. The function sqlColumnTime() calls assignTime() to reach
  this goal.
- In the database driver sql_my.c the function sqlColumnTime() has
  been improved to correct values, if they are outside of the allowed
  range.
- The database driver sql_db2.c has been improved to allow that for
  the functions SQLExecute() and SQLFetch() SUCCESS_WITH_INFO is
  treated as SQL_SUCCESS.
- The database driver sql_post.c has been improved:
  - Inserting and selecting time fields is now supported under
    different operating systems and compilers.
  - The type preparedStmtRecord and the functions freePreparedStmt()
    and sqlPrepare() have been improved such that a prepared statement
    maintains a dbType reference instead of a connection (PGconn).
  - The functions doExecSql() and implicitCommit() have been added.
    These functions are used for autocommit and for transaction
    handling.
- The database driver sql_oci.c has been improved:
  - The function sqlBindTime() has been improved to set the timeZone
    and to use a nanosecond as unit for the fraction of a second.
    There is also a check for situations in which the function
    OCIDateTimeConstruct() fails.
  - The function sqlColumnTime() has been improved to use the function
    OCIDateTimeGetTimeZoneOffset() to retrieve a timeZone and to use a
    nanosecond as unit for the fraction of a second.
- The database driver sql_cli.c has been improved:
  - In case of a DATABASE_ERROR exception the native SQL error is
    assigned to the errorCode.
  - The function freePreparedStmt() has been changed to ignore
    possible errors of SQLFreeStmt().
  - Binding SQL_BLOB and SQL_CLOB parameters is supported now.
  - Retrieving SQL_SS_TIME2 and SQL_XML columns is supported now.
  - Retrieving datetime2 columns in sqlColumnTime() has been improved
    to use the function assignTime().
- The database include files db_lite.h, db_my.h, db_oci.h and db_odbc.h
  have been improved.
- In sql_srv.c the functions connectToServer() and
  connectToLocalServer() have been improved to return a boolean value
  instead of a SQLRETURN value.
- In cmd_rtl.c the functions cmdSetATime() and cmdSetMTime() have been
  improved to use the new function timToOsTimestamp().
- The function determineTdsDefines() has been added to chkccomp.c.
- In exec.c the function suspendInterpreter() has been renamed to
  doSuspendInterpreter().

- In sql_odbc.c the function driverConnect() has been improved to
  search only for a driver, if the driver name is not empty.
- In sql_odbc.c the function sqlOpenOdbc() has been improved to use
  the dbName as DSN (data source name) only, if no driver and no server
  are given.
- In sql_post.c the function setupDll() has been improved to call
  dllOpen() instead of a recursive call of setupDll().
- The new macro ALLOC_RECORD2() has been added to heaputl.h. The macro
  is used in drw_win.c, drw_x11.c, sql_cli.c, sql_fire.c, sql_lite.c,
  sql_my.c, sql_oci.c and sql_post.c.
- The new macros COUNT_GROW_STRI() and COUNT_SHRINK_STRI() have been
  added to heaputl.h. This macros are currently empty. They are planned
  for a heap statistic concerning unused chars in strings with
  capacity.
- In chkccomp.c several improvements have been done. In
  determineFireDefines() a search for the Firebird home directory has
  been added. In determineDb2Defines() the environment variable
  DB2_HOME is used now, to determine the Db2 home directory. In
  determineConsoleDefines() and determineSqlServerDefines() the list
  of DLLs has been improved.
- The heap statistic for strings has been improved to use the string
  capacity instead of the string size.
- The file config.h has been changed to define the macros
  USE_ALTERNATE_NEXT_CHARACTER, USE_INFILE_BUFFER, USE_CHUNK_ALLOCS,
  USE_ALTERNATE_CHUNK_ALLOCS and USE_MAXIMUM_MALLOC_CHECK always. Now
  these macros can have a value of 0 or 1.

20191215:
- The database libraries sql_srv.c and sql_cli.c have been improved to
  allow the connection to a SQL Server database from Linux. The library
  libtdsodbc.so is used to do the actual communication with the
  database.
- The build system of Seed7 has been improved. Logic regarding X11,
  ncurses and the databases has been moved from the makefiles to
  chkccomp.c.
- The build for Linux has been improved to work even if essential
  header files (for X11 or ncurses) are missing. This should only be
  used, if it is impossible to install the development packages of X11
  or ncurses.
- The example program chkdb.sd7 has been improved to do tests for SQL
  Server.
- In the FAQ the explanation of "What is necessary to compile Seed7
  with database connections", has been improved.

  have been improved to work with fwd_term.c and fwd_term.h.
- The file fwd_x11.c has been added. The functions in fwd_x11.c forward
  X11 calls to a shared X11 library. Fwd_x11.c is used, if it is not
  possible to link to a static X11 library.
- The file x11_x.h has been added. This file is used, if no X11 include
  file can be found.
- The files drw_x11.c and gkb_x11.c have been improved to work with
  x11_x.h and x11_x.h.
- The makefiles have been adjusted to work with the new build system.
- The program warn.c has been added. This program writes a warning, if
  header files of X11 or ncurses are missing.
- Documentation has been added to read_me.txt.
- In dll_win.c the function dllOpen() has been improved to assure, that
  a path to a DLL uses a backslash as path delimiter. This is required
  by the function LoadLibrary().
- The files bin/call_cl.bat and bin/call_lib.bat have been removed.

20191117:
- Support for mice with forward and back button has been added to the
  Seed7 run-time library. Many thanks go to Zachary Menzies, for
  driving my focus towards mice with additional buttons.
- Support for the C compiler from Visual Studio 2019 has been added.
  Many thanks go to Alexander Yu. Vlasov for pointing out compilation
  problems with Visual Studio 2019 and for investigating the problems.
- Interpreter and compiler have been improved to support DB2 and SQL
  Server databases.
- In the manual the chapter about the database abstraction API has been
  improved.
- The compiler has been improved to optimize the function replace()
  (action STR_REPL). Special functions (strChRepl() and strChChRepl())
  are used, if the searched or the replaced string consist of one
  character. This works even, if a character is converted to a string
  with the function str().
- Testcases for replace() have been added to chkstr.sd7.
- The program bigfiles.sd7 has been improved to search for the biggest
  directories additionally to the biggest files.
- The libraries keybd.s7i and keydescr.s7i have been improved to
  support KEY_MOUSE_FWD and KEY_MOUSE_BACK.
- The library sql_base.s7i and the programs db7.sd7 and sql7.sd7 have
  been improved to support DB_DB2 and DB_SQL_SERVER.
- In striutl.c the function stri_to_standard_path() has been improved,
  to do a smarter mapping from a DOS/Windows path to the Seed7 standard
  path representation.
- In osfiles.s7i the functions makeParentDirs() and convDosPath() have
  been improved. Now convDosPath() and stri_to_standard_path() use the
  same algorithm to map from a DOS/Windows path to the Seed7 standard
  path representation.
- The function strChChRepl() has been added to str_rtl.c.
- The program chkccomp.c has been improved to define the macros
  REMOVE_REATTEMPTS, SETENV_ALLOWS_KEY_WITH_EQUALS_SIGN and
  GETENV_ALLOWS_KEY_WITH_EQUALS_SIGN.
- The functions determineDb2Defines() and determineSqlServerDefines()
  have been added to chkccomp.c.
- The names of database DLLs (shared libraries) has been moved from
  the makefiles to chkccomp.c.
- The database driver sql_odbc.c has been refactored to be based on
  sql_cli.c. Most of the contents of sql_odbc.c has been moved to
  sql_cli.c and sql_odbc.c now includes sql_cli.c.
- The new database drivers sql_db2.c (for DB2) and sql_srv.c (for SQL
  Server) have been added. Like sql_odbc.c this drivers also include
  sql_cli.c.
- In cmd_rtl.c the function cmdChdir() has been improved to use an
  extended length path only, if it is absolutely necessary. In Windows
  an extended length path starts with \\?\ and can have a length
  greater equal 260. Many subprocesses cannot handle a current working
  directory with an extended length path.
- The makefiles mk_msvc.mak and mk_clangw.mak have been improved to
  write INI files with all environment variables. The INI files are
  seed7/bin/cl_env.ini and seed7/bin/clangenv.ini. This INI files
  contain the environment variables necessary to use the C compiler.
- The program setpaths.c has been improved to optionally write a
  definition of the macro CC_ENVIRONMENT_INI to version.h. The macro
  CC_ENVIRONMENT_INI defines the path of seed7/bin/cl_env.ini or
  seed7/bin/clangenv.ini.
- Support for the configuration values CC_ENVIRONMENT_INI and
  DATABASE_LIB has been added to cc_conf.s7i and cmd_rtl.c (in
  cmdConfigValue()).
- The function unsetenv7() has been added to cmd_unx.c.
- In gkb_x11.c and gkb_x11.c the functions gkbGetc() and
  gkbKeyPressed() have been improved to support KEY_MOUSE_FWD and
  KEY_MOUSE_BACK. Additionally the macro TRACE_EVENTS, to optionally
  trace events has been introduced.
- The makefiles have been improved to create the new library s7_db.a
  (s7_db.lib), which contains all database drivers.
- The files sql_cli.c (former sql_odbc.c) and sql_fire.c have been
  improved to reduce the number of C compiler warnings.
- In sql_cli.c (former sql_odbc.c) the function setDbErrorMsg() has
  been improved to work for database error messages with Unicode
  characters. The function wstri_to_cstri8() has been added to do the
  conversion.
- The file db_odbc.h has been improved to define wide character
  functions instead of ASCII functions. This was needed by sql_srv.c
  because it links dynamically to sqlsrv32.dll, which only defines
  wide character functions.

20191020:
- The support for Emscripten has been improved to allow the compilation
  of Seed7 programs.
- Improvements have been done in sql_odbc.c to support the connection
  with a DB2 database.
- Testcases for pos() and rpos() have been added to chkstr.sd7.
- The compiler has been improved to optimize the functions pos() and
  rpos() (actions STR_POS, STR_RPOS, STR_CHPOS, STR_RCHPOS).
- The program setwpath.c has been improved to work correct in more
  situations (E.g.: If no PATH variable exists, if the path to be added
  is a substring of an existing path, if the first path in the PATH
  variable is to be removed, if there is only on path in the PATH
  variable and this path is to be removed).
- In fil.unx.c the function setupFiles() has been improved to mount the
  file systems for Emscripten and node.js with a better strategy.
- In sql_odbc.c the function sqlStmtColumnName() has been improved to
  work with one call of SQLColAttributeW(), if the length of the column
  name is below a limit. Additionally a parameter of NULL as
  destination for the name has be replaced by a valid address. The
  usage of NULL triggered an error with DB2.
- The configuration value LINKED_PROGRAM_EXTENSION has been added to
  cc_conf.s7i. The linker produces a file with the extension defined by
  LINKED_PROGRAM_EXTENSION. Usually LINKED_PROGRAM_EXTENSION is
  identical to EXECUTABLE_FILE_EXTENSION. Except for Emscripten where,
  the value is ".js".
- The makefiles mk_emccl.mak and mk_emccw.mak have been improved to
  define LINKED_PROGRAM_EXTENSION.
- The compiler (s7c.s7i), the function getProgramName() in arr_rtl.c,
  the function cmdConfigValue() in cmd_rtl.c and the program chkccomp.c
  have been improved to use LINKED_PROGRAM_EXTENSION.
- In chkccomp.c the function determineEnvironDefines() has been
  improved to determine, if getenv() works case sensitive. A definition
  of GETENV_IS_CASE_SENSITIVE, with a value of 0 or 1, is written to
  version.h.
- The function getSearchPathDelimiter() has been added to cmd_rtl.c.
  This function is used if SEARCH_PATH_DELIMITER is 0. In this case
  the search path delimiter must be determined at run-time.
- The function systemForNodeJs() has been added to cmd_rtl.c. This
  function is used for Emscripten and node.js as replacement for the
  C run-time library function system().
- The files sql_fire.c, sql_lite.c, sql_my.c, sql_oci.c, sql_odbc.c
  and sql_post.c have been improved to work correct, if no database
  include file could be found. Normally this should not happen,
  because Seed7 can provide its own database include files.
- The functions getenv7() and setenv7() have been added to cmd_unx.c.
  This functions are used for Emscripten, because of a limitation in
  the Emscripten implementations of getenv() and setenv().
- Documentation comments have been improved in external_file.s7i,
  file.s7i, leb128.s7i, scanfile.s7i, scanstri.s7i and string.s7i.
- Comments explaining the usage of undefined behavior have been added
  to arrlib.c, bstlib.c, set_rtl.c and strlib.c.

  image file format.
- The library browser.s7i has been improved to be more robust regarding
  network events.
- The database drivers have been improved to raise a DATABASE_ERROR,
  if the database library could not be found. The error message of the
  DATABASE_ERROR contains the name of the missing DLL respectively
  shared object library.
- Documentation comments have been improved in 85 library/include files
  (*.s7i). Wrong usages of the word "when" have been replaced by "if".
- Documentation comments have been improved in 96 C source files.
  Wrong usages of the word "when" have been replaced by "if".
- Texts in 9 Seed7 programs (*.sd7) and in a lot of documentation files
  have been improved. Wrong usages of the word "when" have been
  replaced by "if".

20190819:
- A definition of SQL_DRIVER_NOPROMPT has been added to db_odbc.h.
  Many thanks go to Brett Senior for pointing out a fatal compilation
  error in sql_odbc.c, when compiling Seed7 version 2019-08-18 under
  Debian Linux.
- The example program chkdb.sd7 has been improved to write better
  error messages.
- In reflib.c the function ref_select() has been improved to work
  correct, if a derived struct overrides an element of the parent
  struct.

lang/seed7: update to 05_20190818

20190818:
- Interpreter and compiler have been improved to work correct, when
  a derived struct overrides an element of the parent struct. Many
  thanks go to Zachary Menzies, for reporting this error and for
  providing a test program.
- In the FAQ the explanation, why Seed7 uses UTF-32, has been improved.
  An explanation of the database abstraction layer, which provides an
  database independent API, has also been added to the FAQ.
- In the manual the chapter about the deprecated function
  removeAnyFile() has been replaced by a chapter about the function
  removeTree().
- The program db7.sd7 (Database Inspector) has been improved quote a
  table name from the catalog when doing a select.
- The program sql7.sd7 has been improved to allow the execution of SQL
  statements from a file. The function getSqlStatement has been added,
  which reads a semicolon terminated SQL statement from a file.
- The library tar.s7i has been improved to accept extended headers with
  meta data (PAX format) also when a tar file is opened as file system
  with openTar(). The function readMinimumOfHead has been improved to
  do this.
- A code page for JIS X 0201 encoding has been added to charsets.s7i.
- The program err.sd7 has been improved to contain test cases, where
  UTF-16 surrogate characters and non Unicode characters are written as

  opening a database with host name, port and database name. This way a
  database can be opened without an entry in tnsnames.ora. The type
  connectDataRecord and the function setupConnectData() have been added
  to sql_oci.c.
- The functions sqlOpenMy (in sql_my.c) and sqlOpenPost (in sql_post.c)
  have been improved to allow opening a database with host name, port
  and database name. Now host, port and dbName are parameters. Before
  the functions split the parameter dbName into host and database name.
  Specifying a port was not possible.
- In sql_odbc.c the function sqlOpenOdbc() has been improved to allow
  opening a database with ODBC driver name, server name and database
  name. This way a database can be opened without specifying a data
  source in the ODBC Data Source Administrator (in the Control Panel).
  The type connectDataRecord and the functions getRegularName(),
  wstriSearchCh(), wstriSearch(), connectToServer(), connectToDriver()
  and driverConnect() have been added to sql_odbc.c. A definition of
  SQL_NEED_DATA has been added to db_odbc.h.

  remainder_name.

20190523:
- In match.c the function substitute_params() has been fixed to copy
  parameters with expressions instead of calling do_create(). For
  expressions do_create() just creates a reference to the expression

lang/seed7: update to 05_20190303


20190303:
- The makefile mk_tcc_l.mak has been added. This makefile supports
  compiling with the tcc C compiler under Linux.
- The makefile mk_tcc_w.mak has been added. This makefile is
  experimental and supports compiling with the tcc C compiler under
  Windows.
- The example program brainf7.sd7 has been added. Brainf7 is a
  Brainfuck interpreter.
- The example program hilbert.sd7 has been added. Hilbert displays a
  Hilbert curve.
- The example program queen.sd7 has been added. Queen solves the n
  queen problem.
- The example program spigotpi.sd7 has been added. Spigotpi writes
  digits of PI with a spigot algorithm.
- The new library csv.s7i has been added. This library supports
  converting to and from comma-separated values (CSV).
- Several improvements in the Seed7 compiler (s7c) have been done:
  - In flt_act.s7i the function to process FLT_ISNAN has been improved
    to make sure, that the argument of the isnan() macro never contains
    preprocessor directives (e.g. #line directives). Some C compilers
    do not allow preprocessor directives in the argument list of a
    macro. Many thanks go to Alexander Vlasov for reporting this
    problem and for his help to find a solution.
  - In comp/str_act.s7i the function optimize_str_cat has been improved
    to assign the constant parts of strConcatN() outside of the actual
    expression. This might open possibilities to optimize the
    expression.
  - The function process_forward_declaration in the compiler (s7c) has
    been improved to avoid, that a prototype of a forward declared
    function, is written twice.
  - The function process_dynamic_param_implements has been improved to
    generate a switch-statement instead of an if-then-else chain.
    Additionally double entries are avoided now.
  - The function process_const_func_call has been improved to assign
    c_params.temp_assigns to c_expr.temp_assigns instead of
    c_expr.temp_decls.
  - The function processFuncValue has been improved to define the type
    and the function of the actual name parameter only once (with
    defineActualFuncParam()). A redefinition could happen when
    functions, that call functions with name parameters, are inlined.
  - The handling of the option -te (trace exceptions) has been
    improved.
  - The function process_const_func_declaration() has been improved to
    request, that for functions using the result mechanism the result
    is returned, when possible, as c_expr.expr_result. This way
    process_return_value() does not need to copy this string values.
    E.g. When the result of intStrToBuffer(), chrCLitToBuffer(),
    chrStrMacro(), strHeadSlice(), chrStrMacro() or strTailSlice() is
    used as the result value of a user defined function.
  - The function defineFunctype has been added and the function
    getAnyParamToTempAssigns has been improved to provide addresses
    of plain INTOBJECT, FLOATOBJECT, CHAROBJECT, STRIOBJECT and
    BSTRIOBJECT values. In this case the address is taken from a
    temporary variable.
  - In write_file_head() and init_type_constants() the creation of type
    constants has been improved.
- The functions skip() and copyFile() have been added to file.s7i.
- The function makeParentDirs() has been added to osfiles.s7i.
- In cli_cmds.s7i the function doMkdirCmd has been improved to call
  the new function makeParentDirs().
- In tar_cmds.s7i the functions tarXtract and tarCreate have been
  improved to avoid, that the whole file is read into a string. This
  avoids a MEMORY_ERROR, when the file does not fit into a string.
- The function tarXtract has been improved to extract empty regular
  files and to create non-existing parent directories (with
  makeParentDirs())
- In gzip.s7i the functions openGzipFile(), close() and write() have
  been improved, to write the compressed data in blocks with a maximum
  size. This avoids a MEMORY_ERROR, when huge files are compressed.
- In gzip.s7i the function openGunzipFile has been changed to have a
  file as parameter instead of a string. This way it is not necessary
  to read the whole compressed data into a string.
- A variant of the function readGzipHeader has been added to gzip.s7i.
- A variant of the function getAsciiz has been added to bytedata.s7i.
- A variant of the function crc32 has been added to crc32.s7i.
- The program ftp7.sd7 has been improved to support the commands
  !ls -l, !dir, !ls, !pwd, !mkdir and !rmdir.
- The function noCtrlChars has been removed from db7.sd7 and sql7.sd7
  and added to seed7_05.s7i.
- The program chkchr.sd7 has been has been improved to check the
  functions literal() and c_literal().
- Tests for the function str(), when str() assigned to a variable and
  when str() is called via a function, have been added to chkint.sd7.
- Tests for aString[.. pos], aString[pos ..], aString[pos1 .. pos2],
  aString[pos len length], when they are called via a function, have
  been added to chkstr.sd7.
- The example program chkdb.sd7 has been improved to test decimal and
  numeric fields with negative values.
- In x509cert.s7i the constant stdCertificate has been improved to
  have a new validity (until end of 2021).
- The program chkccomp.c has been improved to determine, if
  preprocessor directives are allowed in the argument list of a macro
  invocation (DIRECTIVES_IN_MACRO_ARGUMENTS_OK).
- In fil_rtl.c the functions filBigLng() and filLng() have been
  improved to determine the file length always with os_fseek and
  os_ftell. This guarantees that the correct length is returned, when
  data is written to a file and it has not been flushed.
- The function ftelli64Ext() has been added to fil_win.c. This
  function is used when fseeki64() is available and ftelli64() is
  missing. Either fgetpos() or _telli64() is used to implement
  ftelli64Ext().
- Calls of logFunction have been added in ref_data.c and typ_data.c.
- In sql_my.c the function sqlBindDuration() has been improved.
- In sql_odbc.c the function getNumericAsCStri() has been added.
- In sql_odbc.c the function getNumericFloat() has been improved to
  convert a SQL_NUMERIC_STRUCT to a double via the decimal
  representation.
- In sql_post.c the functions getNumericAsCStri(), getNumericAsStri()
  and getNumericAsFloat have been improved.

  fileno() are not available.
- A definition of 'isatty' and 'fileno' has been added to os_decls.h.
- The mechanism to check for stack overflow has been improved. By
  default the mechanism is deactivated.

20190126:
- The program db7.sd7 (Database Inspector 7) has been improved to
  provide a list of tables and a possibility to view table contents
  from this list.
- The program tar7.sd7 and the library tar.s7i have been improved to
  support Unicode file names.
- The function setupParameters() in sql_fire.c, sql_lite.c, sql_my.c,
  sql_oci.c, sql_odbc.c and sql_post.c has been improved to avoid
  calling malloc(0). Depending on the run-time library malloc(0) may
  return NULL, which would wrongly trigger a MEMORY_ERROR. The
  improvement recognizes this situation and avoids calling malloc(0).
  Other places in the database drivers, where malloc(0) could be called
  have been fixed also.
- The database driver sql_fire.c has been improved:
  - Now the cursor of a prepared statement is closed (with
    isc_dsql_free_statement), when a parameter is bound to it.
  - The opening of a database now appends the extensions .fdb and .gdb,
    when trying to open the database.
- The database driver sql_my.c has been improved:
  - The function processEscapesInStatement has been renamed to
    processStatementStri. Now it removes comments from the statement
    string.
  - The local variable 'param' has been introduced in the parameter
    binding functions. This improves readability by avoiding many
    accesses to the param_array.
  - The local variable 'columnData' has been introduced in the column
    accessing functions. This improves readability by avoiding many
    accesses to the result_array.
  - The function sqlColumnFloat has been improved to accept integer
    fields with all sizes.
- The database driver sql_oci.c has been improved:
  - Now there is a check if all parameters of a prepared statement are
    bound. This check takes place when a prepared statement is
    executed.
  - The function processBindVarsInStatement has been renamed to
    processStatementStri. Now it removes comments from the statement
    string and determines the number of bind parameters.
  - The functions setupParameters and allParametersBound have been
    added and the function resizeBindArray has been removed.
  - The function getFloat has been improved to convert a SQLT NUMBER
    to a double via the decimal representation.
  - The bind functions have been improved to check, that a parameter
    with the given index exists.
  - The bind functions have been improved to allow that the same
    parameter can be bound again with a different bind function (e.g.
    as integer instead of a bigInteger).
  - The function sqlBindStri has been improved to preserve trailing
    blanks in a string.
  - The local variable 'param' has been introduced in the parameter
    binding functions. This improves readability by avoiding many
    accesses to the param_array.
  - The local variable 'columnData' has been introduced in the column
    accessing functions. This improves readability by avoiding many
    accesses to the result_array.
- The database driver sql_odbc.c has been improved:
  - The maximum number of concurrent activities is determined. If the
    number of concurrent activities is limited the function
    sqlExecute() fetches all results and stores them in a prefetch
    buffer. This way several prepared statements can be used in
    parallel even when the ODBC driver does not support concurrent
    activities.
  - The structure resultDescrRecord has been introduced. It contains
    the result properties of a prepared statement column. The structure
    resultDataRecord has been reduced to just contain the actual
    data buffer and length of a result field.
  - The functions freeFetchData, freeFetch, freePrefetched and
    processStatementStri have been added. The function
    processStatementStri removes comments from the statement string.
    This avoids problems with some ODBC drivers.
  - The functions bindResultColumn, bindResult, copyNonBlobBuffers,
    moveBlobBuffers, copyFetchData, prefetchOne, prefetchAll and
    doFetch have been added.
  - Now the cursor of a prepared statement is closed (with
    SQLFreeStmt), when a parameter is bound to it.
  - The function sqlColumnFloat has been improved to accept integer
    fields with all sizes.
- The database driver sql_post.c has been improved:
  - The function processBindVarsInStatement has been renamed to
    processStatementStri. Now it removes comments from the statement
    string.
  - The local variable 'param' has been introduced in the parameter
    binding functions. This improves readability by avoiding many
    accesses to the param_array.
  - The function sqlColumnFloat has been improved to accept integer
    fields with all sizes.
- The example program chkdb.sd7 has been improved. Now it tests several
  corner cases with empty databases, empty statements, comments and
  literals. The tests with integer fields retrieve the fields now also
  as floats.
- Interpreter and compiler have been improved to support the new
  actions SQL_DRIVER, STR_FOR_KEY and STR_FOR_VAR_KEY.
- The library forloop.s7i has been improved to use the new actions
  STR_FOR_KEY and STR_FOR_VAR_KEY.
- Checks for string for loops have been added to chkstr.sd7.
- The library sql_base.s7i has been improved to support the new
  functions driver() and getTableNames(). The function getTableNames
  returns a list of user table names.
- The function sqlDriver has been added to sql_rtl.c.

  allow that the same parameter can be bound again with a different
  bind function (e.g. as integer instead of a bigInteger).
- The database driver sql_lite.c has been improved:
  - The function sqlBindBigRat has been improved to convert a
    bigRational to a double via the decimal representation.
  - The functions sqlColumnBigInt and sqlColumnInt have been improved
    to accept blob values with a decimal content that ends with ".0".
  - The function sqlColumnFloat has been improved to accept integer
    values.
  - The function sqlExecute has been improved to reset a prepared
    statement, when necessary.
- The database driver sql_my.c has been improved:
  - Medium and large blobs are supported now.
  - The function sqlColumnStri() has been improved to read BLOB data.
  - The function processEscapesInStatement() has been introduced. This
    function assures that string literals in prepared statements do not
    allow backslash escape sequences (e.g. \n or \t). This way a
    backslash in a SQL statement has no special meaning (like it is
    common practice in all other SQL databases).
  - The function sqlExecute() has been improved to call
    mysql_stmt_store_result(). This way the complete result set is
    buffered on the client. Doing so avoids the "Commands out of sync"
    error (e.g. which is triggered (without mysql_stmt_store_result()),
    when a new statement is prepared before all data of an old
    statement is fetched).
  - The function resizeBindArray() has been removed.
- The database driver sql_odbc.c has been improved:
  - The function SQLGetTypeInfo is used to determine if the driver
    supports the type SQL_WCHAR.
  - It is recognized when the function SQLDescribeParam() is missing
    and reasonable default values are used instead.
  - The function SQLFreeStmt() is used now without the precondition
    fetchOkay or fetchFinished.
  - The function setupParameterColumn has been introduced. This
    function allocates memory for parameter buffers.
  - One call of SQLDescribeCol() is used to determine the properties of
    result columns instead of many calls of SQLColAttribute().
  - Blob result data is now recognized by data type (SQL_LONGVARCHAR,
    SQL_WLONGVARCHAR or SQL_LONGVARBINARY) instead of data length.
  - The bind functions have been improved to use a switch depending
    on the data type.
  - Calls of SQLBindParameter() have been changed to use parameters
    determined with SQLDescribeParam().
  - At several places switch statements depending on the c_type are
    used.
  - The function sqlColumnDuration has been improved to accept a
    duration in a VARCHAR field.
  - Experimental code to search for an ODBC driver has been added (but
    it is deactivated for now).
- The database driver sql_post.c has been improved:
  - The function setupParameterColumn() has been introduced. This
    function allocates memory for parameter buffers. The buffers are
    part of the bindDataRecord.
  - The conversion of the internal NUMERIC representation to integer,
    float, bigInteger and bigRational values has been improved. Now
    sqlColumnInt() and sqlColumnFloat() can also read NUMERIC data.
  - The functions getNumericAsCStri(), getNumericAsStri(),
    getNumericAsInt(), getNumericAsBigInt(), getNumericAsBigRat()
    and getNumericAsFloat() have been added.
  - The function sqlColumnStri() has been improved to read BLOB data.
  - The memory management has been improved to recogize out of memory
    situations reliable.
  - The handling of exceptions has been improved.
- The function literal() has been added to bigint.s7i, bigrat.s7i,
  boolean.s7i, bstring.s7i, duration.s7i and time.s7i.
- The function integer (it converts a bigInteger to an integer) has
  been added to bigint.s7i.
- The function string (it converts a bstring to a string) has
  been added to bstring.s7i.
- The example program chkdb.sd7 has been improved to test the
  functionality of a database with much more detail. Chkdb.sd7 now
  supports parameters to specify the database to be checked.
- The programs sql7.sd7 and db7.sd7 has been improved to support
  Firebird/Interbase databases.
- The tests of shift operators have been improved in chkbig.sd7.
- The program chkccomp.c has been improved to determine the settings
  for directory access and for the database driver sql_fire.c.
- An #if instruction has been added to dir_win.c, soc_none.c and
  soc_rtl.c, such that the object file can always be linked.
- The function stri_to_cstri8_buf() has been changed to work without
  err_info parameter.
- Experimental code, to avoid the gmp error "overflow in mpz type" for
  shift operations, has been added to big_gmp.c.
- In big_rtl.c, big_gmp.c and big_drv.h the functions bigToInt16(),
  bigToInt32() and bigToInt64() have been changed to have the
  additional parameter err_info.
- The function setupBig() has been added to big_rtl.c and big_gmp.c.
  Additionally interpreter and compiler have been improved to call
  setupBig().
- Documentation comments have been improved in integer.s7i,
  sql_base.s7i, big_gmp.c, big_rtl.c, sql_rtl.c, intlib.c, int_rtl.c
  and striutl.c
- The file soc_dos.c has been renamed to soc_none.c.

Bump PORTREVISION for ports depending on the canonical version of GCC
defined via Mk/bsd.default-versions.mk which has moved from GCC 7.4 t
GCC 8.2 under most circumstances.

This includes ports
 - with USE_GCC=yes or USE_GCC=any,
 - with USES=fortran,
 - using Mk/bsd.octave.mk which in turn features USES=fortran, and
 - with USES=compiler specifying openmp, nestedfct, c11, c++0x, c++11-lang,
   c++11-lib, c++14-lang, c++17-lang, or gcc-c++11-lib
plus, as a double check, everything INDEX-11 showed depending on lang/gcc7.

lang/seed7: update to 05_20180708

20180708:
- The operating system DOS is supported (with DJGPP) again. The tests
  have been done with Dosbox.
- In the compiler (in comp/const.s7i) the actions BIN_AND and BIN_OR
  have been added to the list of special actions. This way the
  functions rotLeft and rotRight (from bin32.s7i and bin64.s7i) are
  implemented as inline functions. This reduces the runtime of sha256
  (from msgdigest.s7i) by 44% (measured with gcc and valgrind, when
  reading data from 200 https connections). The cpu-time of the whole
  test program was reduced by 17%.
- In msgdigest.s7i the functions md4, md5, sha1, sha224 and sha256
  have been improved to use an index for words instead of an index
  for chunks. This simplifies the conversion to 32-bit words.
- In comp/action.s7i the function process_action has been improved to
  use a case-statement instead of multiple if-statements. This reduces
  the runtime of process_action by 39% (measured with gcc and valgrind,
  when the compiler compiles itself). The runtime of the compiler is
  reduced by 2.5%.
- The contents of the libraries enable_input.s7i and enable_output.s7i
  have been moved to the library enable_io.s7i.
- The library comp/expr_util.s7i has been renamed to comp/expr_utl.s7i.
- The program chkccomp.c has been improved to search 64-bit functions
  for fseek() and ftell(). The findings are stored in version.h with
  the macros _FILE_OFFSET_BITS, OS_OFF_T_SIZE, os_off_t, os_fseek and
  os_ftell.
- In chkflt.sd7 the tests for float shift and logarithm of 0.0 have
  been improved.

  have been improved.
- The program chkccomp.c has been improved to work for PostgreSQL
  versions 9.6, 10 and 11.
- In cmd_rtl.c the function getOsCwd has been improved to assure that
  PATH_DELIMITER is used as path delimiter.
- In flt_rtl.c the functions fltDigits and fltSci have been improved,
  to work correct, when printf() with format %f and %e and a huge
  precision crashes. Additionally fltSci() has been improved to work
  correct, when the number of exponent digits written with format %f is
  not fixed.
- In con_wat.c the functions kbdShut and conWrite have been improved
  and the functions term_descr_equal, tcset_term_descr, kbd_init,
  doWriteConsole and doCPuts have been added.

lang/seed7: update to 05_20180601

20180601:
- The library tls.s7i has been improved to support the server_name
  extension and to process handshake messages, that extend over several
  tls message records. Additionally TLS version 1.2 is used now.
- The library x509cert.s7i has been improved to accept a validity with
  times in GeneralizedTime data elements (additionally to times in
  UTCTime data elements).
- The library browser.s7i has been improved to support calling Safari
  under Mac OS X.
- Tests for the functions environment(), getenv() and setenv() have
  been added to chkcmd.sd7.
- A test that checks the sorting of an array of strings has been added
  to chkstr.sd7. This checks the compare() function for strings.
- The compiler s7c has been improved to create better code for the
  option -tf (trace functions). Now the trace functions are added after
  the declarations (such that older C compilers will accept this also).
- In chkflt.sd7 tests for NaN have been grouped together.
- In chkovf.sd7 tests for the binomial coefficient have been split into
  groups.
- The program chkccomp.c has been improved to define the macros
  LIMITED_CSTRI_LITERAL_LEN, LIMITED_ARRAY_LITERAL_LEN,

  DEFINE_WGETENV, DEFINE_WSETENV, os_environ, os_getenv, os_setenv,
  os_putenv, DELETE_PUTENV_STRING, DEFINE_WSTATI64_EXT,
  DEFINE_STRUCT_STATI64_EXT, DEFINE_FSTATI64_EXT, os_lstat, os_stat,
  os_fstat, os_stat_struct, os_fstat_struct, HAS_SELECT and HAS_MMAP.
- In int_rtl.c the macro DECIMAL_DIGITS has been improved to work with
  unsigned numbers.
- In str_rtl.c the function strCmpGeneric() has been changed back to
  the old behaviour. Now strCmpGeneric() and strCompare() have again
  the same behaviour. It has turned out that sorting an array of
  strings worked wrong, when the program was compiled.
- In pcs_win.c the function prepareCommandLine has been improved and
  the function copyQuotedPart has been added. Now the command line
  created for CreateProcessW() has fewer quoted parameters. Now
  parameters that contain a space or a quotation (") or a control
  character or a character byond ASCII are quoted. All other parameters
  are not quoted.
- Definitions of USE_MMAP, os_environ, os_fstat, DEFINE_WSTATI64_EXT,
  os_lstat, os_stat, os_stat_orig, os_stat_struct, os_fstat_struct,
  DEFINE_WSETENV, os_setenv, os_putenv and USE_DIRENT have been removed
  from the makefiles.

  use case statements with strings.
- The operator &:= has been added to the libraries bitsetof.s7i and
  bitset.s7i.
- The function rand() has been added to the library hashsetof.s7i. This
  function returns a random element from a hash set.
- The compiler (s7c) has been improved to generate code that uses
  memcpy or memmove to copy and create arrays of simple value types
  (e.g. array integer). The destruction of arrays of simple value types
  has also been simplified.
- The compiler has been improved to optimize the action SET_RAND.
- The compiler optimizations for the actions SET_DIFF, SET_UNION and
  SET_UNION_ASSIGN has been improved.
- In the compiler (in comp/const.s7i) the actions BLN_ICONV1,
  BLN_ICONV3, CHR_ICONV3 and SET_RAND have been added to the list of
  special actions. The compiler implements functions, which just call
  one of the special actions as inline functions.
- Interpreter and compiler have been improved to support the actions
  HSH_RAND_KEY and SET_INTERSECT_ASSIGN.
- Tests for the functions card() and rand() for the type set of string
  have been added to chkset.sd7.
- Tests for intersection assignments ( &:= ) have been added to
  chkset.sd7.
- In s7c.sd7 the code to call C compiler and linker has been
  refactored.
- The compiler has been improved (in comp/prc_act.s7i) to use the
  function hshIdxDefault0() instead of hshIdxWithDefault() for case
  statements with hashsets.
- The code generation of the compiler has been improved to trigger the
  signal SIGFPE with a call of triggerSigfpe().
- The compiler has been improved to insert diagnostic line information
  (e.g.: #line 64 "logfile.s7i") into code for the actions ARR_CPY,
  BLN_AND, BLN_OR, ITF_CPY, PRC_IF, PRC_IF_ELSIF, PRC_IF_NOOP
- The compiler has been improved to insert diagnostic line information
  for inlined functions.
- The configuration values in cc_conf.s7i have been improved.
  SWITCH_WORKS_FOR_INT64TYPE, CC_OPT_OPTIMIZE_1, CC_OPT_OPTIMIZE_2 and
  CC_OPT_OPTIMIZE_3 have been added. SYSTEM_DB_LIBS has been renamed
  to ADDITIONAL_SYSTEM_LIBS. HAS_SIGACTION, SIGNAL_RESETS_HANDLER and
  DO_SIGFPE_WITH_DIV_BY_ZERO have been removed.
- The program chkccomp.c has been improved. Now it determines the name
  of the NULL device (/dev/null or NUL:), the system socket library
  (unix sockets or winsocket), the method to read directories, the
  bigInteger implementation used (big_rtl.c or big_gmp.c) and the
  support for switch statements with 64-bit values.
- Documentation comments have been added or improved in bigint.s7i,
  integer.s7i, bitsetof.s7i, bitset.s7i, hashsetof.s7i, cc_conf.s7i,
  fil_rtl.c, dir_drv.h, cmd_rtl.c, set_rtl.c, str_rtl.c and striutl.c.
- In set_rtl.c the function setIntersect() has been improved to create
  a smaller intersection result, if possible.

  improved to use hshIdxDefault0() instead of hshIdxWithDefault().
- In big_gmp.c the function bigDivRem has been improved to initialize
  the remainder.
- In str_rtl.c and strlib.c the function strelem_memcmp has been
  renamed to memcmp_strelem.
- In str_rtl.c the function strCmpGeneric has been changed to avoid
  calls of memcmp_strelem(), when the string sizes differ. This
  differs from the behaviour of strCompare, but the difference is not
  important, because strCmpGeneric() is only used for string
  comparisons of hash keys (in compiled programs).
- In striutl.c the function conv_to_cstri has been rewritten to return
  the C string, when the function succeeds, and to work without the
  parameter err_info.
- In striutl.c the function stri_to_bstriw has been rewritten to use
  an err_info parameter.
- In striutl.c the functions with loop unrolling inspired by Duff's
  device have been rewritten.

  compilers, that do not support switch statements with 64-bit values.
- Definitions of NULL_DEVICE, USE_GETADDRINFO, USE_WINSOCK and
  BIGINT_LIB_DEFINE have been removed from the makefiles.

20180401:
- The new library logfile.s7i has been added. It defines the interface
  logFile. A logFile works like a normal file unless the log file
  has the value STD_NULL. When a logFile has the value STD_NULL string
  expressions written to the logFile are not evaluated. This reduces
  the overhead, when logging is turned off.
- The bas7.sd7 (basic interpreter) example program has been improved.
  The logging is now done via the new logFile type. This improves the
  performance, when no logging is done. Several DATA statements in one
  line are processed correctly now. Support for IF GOSUB and DISPLAY
  statements and for the function COMMAND$ has been added.
- Tests of nested bigInteger for loops have been added to chkbig.sd7.
- A test with the assignment of a hash variable to itself have been
  added to chkhsh.sd7.
- Tests of the replace function have been added to chkstr.sd7.
- In striutl.c the functions conv_from_os_stri, cstri8_to_stri and
  cstri8_buf_to_stri have been improved. Now they call realloc()
  only, when the size has changed. This improves the performance of
  conv_from_os_stri by 32% (measured with gcc and valgrind, when
  reading a directory).
- In str_rtl.c the function strUtf8ToStri has been improved to call
  realloc() only, when the size has changed.
- In cmd_rtl.c the functions add_stri_to_array and
  complete_stri_array have been renamed to addStriToRtlArray and
  completeRtlStriArray respectively. The renamed functions have also
  been improved to work with a simpler parameter list. Together with
  the improvement of conv_from_os_stri this improves the performance
  of cmdLs by 14% (measured with gcc and valgrind, when reading a
  directory).
- In cmdlib.c the function cmd_ls has been rewritten to be based on
  cmdLs. The functions cmp_mem and read_dir have been removed.
- In cmdlib.c the main loop in the function toArrayType has been
  optimized for performance.
- In str_rtl.c the function add_stri_to_array has been renamed to
  addCopiedStriToRtlArray and the function completeRtlStriArray has
  been introduced. The code of addCopiedStriToRtlArray has also been
  improved to work with a simpler parameter list.

  the boolean and char random number generator.
- The compiler (s7c) has been improved (in comp/destr.s7i) to define
  interface destructors, which take all possible implementation
  types into account. Additionally a switch statement is used instead
  of an if-then-else chain. Double entries are also avoided now.

13:19 gahr 

lang/seed7: update to 05_20170501

With this update, lang/seed7 depends on a number of database client libraries
(MySQL, SQLite, unixODBC and PostgreSQL). The reason for this is that the
configuration stage doesn't allow to specify which database drivers to use, but
rather automatically links against what's installed. This would cause
non-tracked dependencies in the case the user building the port happens to have
any of the drivers installed at build time.

20170501:
- The example program diff7.sd7 has been added. This program compares
  two files line by line.
- The example program hd.sd7 has been added. This program writes a
  hexdump of a given file.

- The compiler has been improved to optimize expressions like
  bin64(aBigExpression mod aPowerOfTwo).
- The library vectorfont.s7i has been improved to allow scaling of
  vector fonts.
- The dialog element passwordField has been added to cgidialog.s7i.
  The passwordField dialog element allows entering a password without
  readable echo.

- In array.s7i the for-until loops for arrays have been improved to
  work correct, when the until-condition uses the for variable.
- In cli_cmds.s7i the functions getCommandParameter,
  getUnixCommandParameter and getDosCommandParameter has been
  improved to recognize when a closing quote is missing.
- In cli_cmds.s7i in the function processCommand the handling of
  external commands with redirection of stdin has been improved.
- The functions xyArray and scale have been added to graph.s7i.
- In seed7_05.s7i the exception DATABASE_ERROR has been introduced.
- The programs sql7.sd7 and chkdb.sd7 have been improved to use the
  new exception DATABASE_ERROR.
- A parse operator for dbCategory has been added to sql_base.s7i.
- The pictures return_pic and right_arrow_pic have been added to
  pic32.s7i and pic16.s7i.
- The function checkBinBinaryWithBigMod has been added to chkbin.sd7.
  This function checks the optimizations done with expressions like
  bin64(aBigExpression mod aPowerOfTwo).
- In tls.s7i the type securityParameters has been renamed to
  tlsParameters. The functions showMsg and showMsgType have been
  renamed to showTlsMsg respectively showTlsMsgType.
- In tls.s7i the generation of CLIENT_HELLO, SERVER_HELLO,
  CERTIFICATE, SERVER_HELLO_DONE, CLIENT_KEY_EXCHANGE,
  CHANGE_CIPHER_SPEC, FINISHED, ALERT and APPLICATION_DATA messages
  has been improved.
- In int_act.s7i the types addSubElementType and

20170129:
- The new library filesys.s7i has been added. It defines the interface
  fileSys. Files of TAR, ZIP and JAR achives and files from FTP and
  the operating system can be accessed via the fileSys interface. The
  file system changes are work in progress.
- The libraries tar.s7i, zip.s7i, ftp.s7i and osfiles.s7i have been
  adjusted to implement the new interface fileSys.
- Definitions of the types fileType, filePermission and fileMode have
  been moved from osfiles.s7i to the new library filesys.s7i.
- A definition of the file system osFiles has been added to
  osfiles.s7i.

  extends fileSys with the functions listDir, getActiveMode,
  setActiveMode, getAsciiTransfer and setAsciiTransfer.
- The functions retrieve and store have been removed from ftp.s7i and
  the function open (to open a file) has been added.
- The new library ftpserv.s7i has been created. This library allows,
  that the backend of an FTP server is also a file system. Most of
  the contents of ftpserv.s7i has been moved from ftpserv.sd7.
- The functions setUpHead, tarTell, tarXtract and tarCreate have been
  moved from tar.s7i to the new library tar_cmds.s7i.

  bin32.s7i. This functions convert values between single precision
  float and bin32.
- The conversion functions bin64 and float have been added to
  bin64.s7i. This functions convert values between double precision
  float and bin64.
- The functions getBitLsb and getBitsLsb have been added to
  bitdata.s7i. This functions read bits from a file in the direction
  from LSB (least significant bit) to MSB (most significant bit).
- The operator |:= has been added to the libraries bitsetof.s7i and
  bitset.s7i.
- The type void has been improved to allow writing a void value.
  This allows that calc7.sd7 can execute procedures.
- The new library inflatefile.s7i has been added. It allows to
  uncompress data from a file with the Inflate algorithm. In contrast
  to inflatefile.s7i the functions from inflate.s7i assume that the
  compressed data is in a string.
- A test of the tar header checksum has been added to tar.s7i.
- A support for long link paths has been added to tar.s7i.
- The function readMinimumOfHead has been added to tar.s7i. With this
  function opening a tar archive can be done faster.
- The functions fileMode and getMTime in zip.s7i have been improved
  to recognize modes and times from different operating systems.
- In zip.s7i the function rposOfMagic has been improved to work with
  one call of seek() and one gets(). This way the function is faster,
  when the file is not a ZIP file.
- In zip.s7i the functions get_local_header, get_central_header and
  get_end_of_central_directory have been improved to read the fixed
  size part of the header with one statement and to convert the data
  afterwards. This improves the performance of get_central_header by
  about 10%.
- In zip.s7i a map of extra header fields has been introduced.
- In zip.s7i the function getContent has been renamed to getFile.
  Additionally the function has been improved to work when the local
  header does not contain the compressed size. In this case the new
  library inflatefile.s7i is used.

  library ftpserv.s7i.
- In seed7_05.s7i the function to convert an integer to a string with
  a given base has been improved.
- Interpreter and compiler have been improved to support the actions
  BIN_CARD, SET_UNION_ASSIGN and STR_FOR.
- In the compiler (s7c) the generation of inline code for the actions
  STR_RANGE and STR_SUBSTR has been improved. When some parameters are
  constant checks can be done at compile-time instead of run-time.
- In drw_x11.c the function redraw() has been improved and the new
  function setupBackup() has been added. This changes have been done
  to handle EXPOSE events correctly, when backing store has the value
  WhenMapped.
- In runerr.c the functions continue_question, run_error, empty_value
  and var_required have been changed to allow the repacement of the
  current exception with a new one.
- The function str_for has been added to strlib.c.

20161231:
- The function toArray has been added to the libraries bitset.s7i,
  bitsetof.s7i and hashsetof.s7i. This function creates an array
  with all values from a given set.
- Experimental functions to access TAR and ZIP archives as file system
  have been added to tar.s7i and zip.s7i. This is work in progress, so
  the API might change.
- The compiler has been improved to work correctly with a C++ compiler
  backend (Now it uses strRaiseError insead of intRaiseError) for the
  code generated for BIN_RADIX and INT_RADIX.
- The compiler has been improved to use sigaction(), when available
  (HAS_SIGACTION is TRUE).
- The compiler has been improved to reactivate the signal handler,
  when necessary (SIGNAL_RESETS_HANDLER is TRUE).
- Testcases for the parse function with whitespace and control
  characters have been added to chkbig.sd7.
- in big_gmp.c the functions bigParse and bigParseBased have been
  improved, to raise RANGE_ERROR when whitespace characters are in the
  string.
- The configuration values HAS_SIGACTION and SIGNAL_RESETS_HANDLER
  have been added to cc_conf.s7i.
- The program chkccomp.c has been improved to define
  SIGNAL_RESETS_HANDLER.

  integer.s7i, int_rtl.c, stat_win.c and tim_win.c.
- The compiler has been improved to optimize expressions, where
  several terms are added or subtracted in combination with the
  functions succ or pred. It is possible to combine adjacent constant
  terms at compile time. This simplifies overflow checks.
- The compiler has been improved to optionally generate programs,
  that trace function calls. This is activated with the option -tf.
- Checks have been added to chkint.sd7, where several terms are added
  in combination with the functions succ or pred.
- The functions wstati64Ext (in stat_win.c) and alternate_utime (in
  tim_win.c) have been improved to avoid the strange time adjustments
  of windows for Daylight Saving Time: For the same file different
  times are retrieved respectively set in summer and winter. Now the
  times do not depend on the time when they are retrieved or set.
- In stat_win.c a check for wildcards in a path has been removed from
  wstati64Ext.
- The performance of dirRead in dir_rtl.c has been improved by 10%
  (measured with gcc and valgrind). A smarter check for the
  directories . and .. reduces the CPU time used.
- In cmd_rtl.c the functions remove_dir and copy_dir have been
  improved with a smarter check for the directories . and .. to
  reduce the CPU time used.
- The function getSearchPath in cmd_rtl.c has been improved to work
  correctly, when there is no environment variable named PATH.
- Definitions of macros to check the st_mode field of struct stat
  (e.g. S_ISDIR, S_ISREG, etc.) have been moved from fil_rtl.h to
  stat_drv.h.
- The program chkccomp.c has been improved to work correct, when
  C compiler options are separated by linefeeds (\n). In this case the
  linefeeds are replaced by spaces. The linefeeds are used in
  cc_conf.s7i to allow the definition of SYSTEM_DB_LIBS as an array of
  database libraries.
- In sudo.c the call of ShellExecute() has been replaced by a call of
  ShellExecuteA().
- A definition of FMT_T, a printf format for time_t values, has been
  added to common.h.
- The makefile mk_clangw.mak has been improved to use the library
  extension ".lib".
- Calls of logFunction and logError have been added or improved in
  cmd_rtl.c, cmd_win.c, gkb_win.c, flt_rtl.c, int_rtl.c, pcslib.c,
  reflib.c, rfllib.c, stat_win.c and tim_win.c.
- In dir_rtl.c the function readVolumeName has been improved to
  consider only directories as volumes.
- In int_rtl.c the functions uint_mult, uint2_mult and uint2_add
  have been renamed to uintMult, uint2Mult and uint2Add respectively.
- In stat_win.c the functions filetime_to_unixtime and
  fileattr_to_unixmode have been renamed to fileTime2UnixTime and
  fileAttr2UnixMode respectively.
- In tim_win.c the function alternate_utime has been improved to
  avoid calling os_utime_orig, because the utime functions of Windows
  do different time adjustments for the same time in summer and
  winter.

- The examples about multiple dispatch in the FAQ and in the manual
  have been changed.
- In dir_win.c the functions opendir and wopendir have been improved
  to work correctly, when a volume is empty. FindFirstFile returns
  INVALID_HANDLE_VALUE, when the path refers to an empty volume
  (a directory that does not contain the . and .. directories).
  After FindFirstFile fails GetFileAttributesEx is used to recognize
  empty volumes.
- In stat_win.c the function wstati64Ext has been improved to
  recognize empty volumes correctly. Now GetFileAttributesEx is used
  instead of FindFirstFile to get information about a file.
- The function openVolumeList has been moved from cmd_win.c and
  cmd_unx.c to dir_win.c.
- The definition of volumeListType has been moved from cmd_drv.h to
  dir_win.h.
- In str_rtl.c the function strAppendN has been improved to work
  correctly, when an appended string is identical to the destination
  or a slice of it. There was already code to handle this case, but
  this code could access freed memory in rare situations.
- The makefiles mk_nmake.mak and mk_msvc.mak have been changed to
  include the file 'macros' before the macro SYSTEM_DB_LIBS is used.
- Rand functions have been added to bin32.s7i and bin64.s7i.

lang/seed7: update to 05_20160229

Changes:

- The function fltCmp in flt_rtl.c has been improved to work correct
  in the case that isnan returns neither 0 nor 1 (Many thanks go to
  Arnel L. for reporting this problem).
- The function determineGetaddrlimit in chkccomp.c has been improved
  to include <sys/types.h> before <sys/resource.h>. FreeBSD needs
  that to work correctly (Many thanks go to Pietro Cerutti for
  providing a fix and explaining the background).
- The function getOsCwd has been added to cmd_rtl.c. With this
  function it is possible to read (e.g. under Linux) a current
  working directory that is longer than PATH_MAX.
- Documentation comments have been improved in encoding.s7i.
- The program chkccomp.c has been improved to write definitions of
  USE_DIRENT, USE_DIRWIN, OS_WIDE_DIR_INCLUDE_DIR_H, os_DIR,
  os_dirent_struct, os_opendir, os_readdir, os_closedir,
  INCLUDE_SYS_UTIME, os_utimbuf_struct, USE_ALTERNATE_UTIME,

  os_remove, os_rename, os_system, os_fopen, os_popen, os_pclose,
  DEFINE_WGETENV, os_getenv
- The functions keys_helem and values_helem in hshlib.c and
  hsh_rtl.c have been improved to use a loop instead of a tail
  recursion. For compilers that don't recognize the tail recursion
  this results in a speed improvement (Gcc recognizes tail
  recursions so there is no speed improvement).
- The functions free_helem and free_hash in hsh_rtl.c have been
  improved to stop searching for helems as soon as the last helem
  has been freed.
- The functions helem_data_to_list and helem_key_to_list have been
  improved to use a loop instead of a tail recursion (see above).

- Update to 05_20140907
  Changes:
  * The function setSearchPath has been added to the library
    process.s7i.
  * The compiler has been improved to write an error message, when the
    sets of a case-statement overlap. Until now this situation was only
    recognized by the C compiler.
  * The interpreter has been improved to raise an exception, when the
    current value of a case-statement is element of two sets.
  * There have been changes in the libraries makedata.s7i and make.s7i.
  * The macro expansion in makedata.s7i has been changed. Now all macro
    expansions (except the expansions of internal macros) are done with
    the function applyMacros.
  * In makedata.s7i the function applyMacros has been improved to
    process the makefile macro functions wildcard, error and warning.
  * The functions evalFunction and getMacro, that where used to do
    macro expansion when the makefile is read, have been removed.
  * The code to read the definition of recursively expanded variables
    has been changed to do no macro expansion. This macros are expanded
    when they are used.
  * The library make.s7i has been improved to read the parameters
    for the commands rm, cp, and mv as Unix shell parameters (with the
    function getUnixCommandParameter).
  * The library make.s7i has been improved to read the parameters
    for the commands del, copy, xcopy and move as Dos/Windows batch
    parameters (with the function getDosCommandParameter).
  * Interpreter and compiler have been improved to support the action
    CMD_SET_SEARCH_PATH.
  * The batch file bin/call_gcc.bat has been changed to work correctly,
    when it is called from any directory.
  * Writing error messages in error.c has been changed to use prot_...
    functions instead of printf.

- Update to 05_20140817

  Changelog:

  * The chapter about files in the manual has been improved.
  * Variants of the for-each-loop with an until condition have been
    added to array.s7i.
  * The parse operator for characters has been improved to accept only
    strings with a length of 1.
  * The function trimValue has been introduced. This function trims a
    string such that it can be converted to a specified type.
  * The exception handlers for RANGE_ERROR have been removed from the
    functions read and readln in enable_input.s7i. The functions read
    and readln now raise range RANGE_ERROR when the conversion to the
    target type fails.
  * Occurances of io_ok, io_error, io_empty and io_filled have been
    removed from the libraries. This undocumented feature was not used
    for years. The function succeeds and the functions read and readln
    with default value are better suited for error checking, when data
    is read.
  * The exception handlers in interpreter and compiler have been
    improved to allow an otherwise part.
  * The function succeeds has been introduced. This function executes
    a statement and returns TRUE when no exception occurs.
  * The example programs nicoma.sd7 and savehd7.sd7 have been improved
    to use the new function succeeds.
  * The parse operator for float has been changed to raise RANGE_ERROR
    when leading whitespace is found.
  * The library make.s7i has been improved to accept the commands
    erase, xcopy, mv, move and rem.
  * The library makedata.s7i has been improved to accept the macro
    functions subst and patsubst.
  * The reading of rules in makedata.s7i has been improved to read
    commands without macro substitution. The macros in commands are
    substituted just before the commands are executed.
  * The make functions in make.s7i have been changed to raise
    FILE_ERROR when a command fails.
  * The function applyMacros in makedata.s7i has been improved to
    accept macro functions and the shorthands of patsubst.
  * The function replaceSuffixes in makedata.s7i has been improved to
    accept pattern substitution with the % character.
  * In the library make.s7i the logging has been removed from the
    functions doRm, doCp, doPwd, doEcho, doCd, doMake, doOneCommand,
    doCommands and processCommand.
  * The program chkflt.sd7 has been adjusted to work with the strict
    parse operator for float.
  * Interpreter and compiler have been improved to support the actions
    PRC_BLOCK_CATCH_ALL and PRC_BLOCK_OTHERWISE.
  * The program sudo.c has been improved to work without upper limit
    for the parameter length.
  * The functions checkIfOutsideRange and negate have been added to
    int_act.s7i.

- Update to 05_20140803
  Changes:

  * The handling of ctrl-c has been changed to work better under
    windows.
  * The runtime of the function intPowOvfChk in int_rtl.c has been
    reduced to 57% (measured with gcc and valgrind).
  * The generation of code in the compiler for the action INT_POW has
    been improved. When the base is a negative power of two the
    exponentiation is done with a shift instead of a call of intPow
    (respectively intPowOvfChk).
  * The overflow checking for INT_POW in the compiler has been
    improved. When base or exponent is known the overflow checking is
    done with inline code and intPow is called instead of intPowOvfChk.
  * Documentation comments have been added to bitsetof.s7i
  * Tests for ** have been added to chkint.sd7 and chkovf.st7
  * The tests for * and *:= in chkovf.st7 have been reorganized.
  * An interrupt_flag has been introduced in the interpreter. This flag
    is used for exception handling and for signal handling. Exceptions
    set interrupt_flag and fail_flag (with the macro set_fail_flag).
    Signals set only the interrupt_flag (file sigutl.c). The
    interrupt_flag is handled in exec_action (file exec.c).
  * The functions signal_name, handle_signals, handle_segv_signal,
    handle_term_signal and activate_signal_handlers in sigutl.c have
    been improved.
  * The functions continue_question, write_curr_position and
    show_signal in runerr.c have been improved.
  * The functions handle_int_signal, readChar, doGetcFromTerminal,
    doGetsFromTerminal, doLineRead, doLineReadFromTerminal, doWordRead,
    doWordReadFromTerminal, filGetcChkCtrlC, filGetsChkCtrlC,
    filHasNextChkCtrlC, filLineReadChkCtrlC and filWordReadChkCtrlC
    have been added to fil_rtl.c. This functions support reading from
    a terminal with a check for ctrl*c. This functions are used by the
    interpreter (file intlib.c).
  * Tracing has been added to functions in int_rtl.c.
  * Configuration defines for CTRL_C_SENDS_EOF,
    SIGNAL_HANDLER_CAN_DO_IO and INT64TYPE_NO_SUFFIX_BUT_CAST have been
    added to makefiles.

- Update to 05_20140720

  Changes:

  * The compiler has been improved to generate overflow checking code
    by default. The generation of overflow checking code can be
    switched off with the option -so.
  * The exception OVERFLOW_ERROR has been introduced. It is raised by
    the interpreter and by compiled programs when an integer overflow
    occurs.
  * A paragraph about integer overflow and the installation of Seed7
    has been added to the FAQ.
  * The chapter about exceptions in the manual has been improved.
  * The program chkovf.sd7, which checks the recogition of integer
    overflows, has been added.
  * Checks for +, -, *, rem, mod, <<, +:=, -:=, *:=, succ, pred, incr
    and decr have been added to chkint.sd7.
  * Checks for the lpad operator have been added to chkstr.sd7.
  * The compiler option -r has been replace by the option -sr.
  * The program calc7.sd7 has been improved to report MEMORY_ERROR and
    OVERFLOW_ERROR.
  * The library make.s7i has been improved such that make7.sd7 accepts
    echo (and echo.) statements without parameters.
  * The function eof has been defined for the type tlsFile in tls.s7i.
  * The function gets in tls.s7i has been improved.
  * The function getHttp in gethttp.s7i has been improved to avoid an
    endless loop when eof has been reached.
  * The function memcpy_from_strelem has been added to striutl.c. This
    function uses loop unrolling inspired by Duff's device and a trick
    with a binary or (|=) to check for allowed values.
  * The functions filWrite, socWrite and bstParse have been changed
    to use memcpy_from_strelem. The reduction in runtime has been
    measured with gcc and valgrind. The runtime of filWrite, socWrite
    and bstParse has been reduced to 53%, 61% and 56% respectively.
  * Documentation comments have been added to integer.s7i, bin32.s7i,
    intlib.c and striutl.c.
  * The compiler has been improved to generate overflow checking code
    for *, <<, >>, *:=, <<:= and >>:= .
  * The generation of overflow checking code for the operators rem and
    mod has been improved.
  * Checks for overflow, division by zero, numeric error and index out
    of bounds in compiled programs now use the macros ovfChk, divChk,
    numChk and idxChk. This macros inform the C compiler about the
    unlikeliness of an exception.
  * The function fltIPow has been improved to avoid a signed integer
    overflow, when the exponent is the most negative integer.
  * The primitive actions INT_ULSHIFT and INT_ULSHIFT_ASSIGN have been
    added and supported in interpreter and compiler.
  * A version of the function uint_rand, which uses 128-bit integers,
    has been added to int_rtl.c.
  * The function raise_error3 in runerr.c has been renamed to
    interprRaiseError.
  * The configuration values INT128TYPE, UINT128TYPE and MACRO_DEFS
    have been added to cc_conf.s7i. The configuration value
    SIGILL_ON_OVERFLOW has been replaced with OVERFLOW_SIGNAL.
  * The functions constValueIsEqual, checkRangeFromZero,
    process_const_int_lshift, process_const_int_lshift_assign,
    process_const_int_rshift_assign, process_const_int_mult,
    process_const_int_mult_assign, process_const_int_ulshift_assign,
    process_const_int_ulshift and process_const_int_urshift_assign
    have been added to int_act.s7i.
  * The function intExpr in chkbig.sd7, chkexc.sd7, chkint.sd7 and
    chkstr.sd7 has been changed to make sure that the C compiler
    cannot evaluate it at compile time.
  * The runtime of the functions str_lpad, strLpad and strLpadTemp has
    been improved.

- Update to 05_20140706
  Changes:
  * The interpreter has been improved to recognize integer overflow.
    Now the exception NUMERIC_ERROR is raised, when a program triggers
    an integer overflow. The checks for overflow are done in software,
    but the overhead is small. With overflow checks the interpreter
    needs 0.5% (zero point five percent) more run-time to execute the
    program chkint.sd7 (verified with gcc and valgrind).
  * A chapter about the Seed7 Structured Syntax Description (S7SSD)
    has been added to the manual.
  * The for-until-loops in bitset.s7i and bitsetof.s7i have been
    improved such that the for-variable has the correct value, when it
    is used in the until-condition.
  * The function replaceN has been added to string.s7i. This function
    does replacements until no occurance of the target string is left.
    This function is used by toStdPath to replace multiple occurances
    of a character by one occurance (replace("/a///b////c", "//", "/")
    returns "/a/b/c").
  * The program calc.sd7 has been renamed to calc7.sd7.
  * The program calc7.sd7 has been changed to accept the commands
    'quit' and 'exit'. This commands can be used to exit the program.
    The possibility to leave the program with an empty input line has
    been removed.
  * The program calc7.sd7 has been improved to write the name of the
    exception, when it has been raised.
  * The compiler has been improved to allow the generation of overflow
    checking code. Overflow checking code can be generated for the
    operators +, -, **, +:= and -:= and the functions abs, succ, pred,
    incr and decr. Until the rest of the functions is implemented and
    enough tests have been added to chkint.sd7 the functionality is
    switched off.
  * The template FOR_UNTIL_DECLS has been added to forloop.s7i. This
    template defines for-loops with a condition.
  * The function abs has been moved from the library math.s7i to the
    library float.s7i.
  * Checks for addition, subtraction, multiplication, power and abs
    have been added to chkint.sd7.
  * In the compiler the statements to write the C prototypes have been
    moved from s7c.sd7 to functions in the files comp/xxx_act.s7i
    (xxx is the abbreviation for the corresponding primitive type).
  * The functions getReference getParameterAsReference have been added
    to comp/expr_util.s7i.
  * The function isit_bool from objutl.c has been replaced by the macro
    isit_bool (defined in objutl.h). This improves the speed of the
    interpreter.
  * The function set_card has been improved to call setCard, which
    computes the cardinality of a set much quicker.

  Changes:

  * The makefile mk_freebsd.mk has been changed to work with the new
    version of chkccomp.c. Thanks go to Pietro Cerutti for pointing out
    the problem.
  * The self extracting Seed7 package for windows has been improved to
    use gcc version 4.8.1 instead of 4.5.0.
  * The new function removeTree, which removes a directory tree, has
    been introduced in osfiles.s7i. The function removeAnyFile, which
    has been used for the same purpose, is deprecated. Deprecated
    functions will be removed in a future version.
  * Checks for hash tables with character keys have been added to
    chkhsh.sd7.
  * The test program "chkcmd.sd7" has been added. This program checks
    functions that copy, move and remove files. Note that windows has
    race conditions when files are copied, moved and removed quickly in
    succession. This bug of windows cannot be fixed in a runtime
    library.
  * The function temp_name_in_dir has been added to striutl.c.
  * The typedef of socketType in common.h has been changed such that
    socketType is always int.
  * Functions in soc_rtl.c, pol_sel.c and pol_unx.c have been changed
    to use the type os_socketType.
  * Tracing statements in hsh_rtl.c, cmd_rtl.c, drw_win.c and drw_x11.c
    have been changed to use the FMT_ strings from common.h. This way
    the tracing is more portable.
  * Under Windows the functions cmdRemoveFile and cmdRemoveTree now
    rename a file before it is removed. When the renaming fails the
    directory is left intact. This avoids half removed directory trees
    under Windows, when a process has the current working directory
    somewhere in the directory that is to be removed. The renaming also
    lowers the probability of race conditions under Windows, but they
    still can happen.
  * The function checkMoveDirectory has been added to chkccomp.c.
  * The target make7 has been added to the makefiles. With 'make make7'
    an executable of the make7 program is generated and placed in
    seed7/bin.

  * The compiler has been refactored. Code has been moved from s7c.sd7
    to several compiler libraries. The compiler libraries are licensed
    with the GPL and can be found in seed7/lib/comp. The refactored
    compiler is the first compiler of the 3.0 series.
  * The chapter in the manual about the foreign function interface has
    been improved.
  * Checks for parse and str have been added to chkflt.sd7 and
    chkint.sd7.

    numericSizes and numericProperties.
  * Usages of the macro logError have been added to cmd_rtl.c and
    cmd_unx.c.
  * The stack size defined in mk_mingc.mak, mk_mingw.mak, mk_msys.mak
    and mk_nmake.mak has been changed from 4194304 to 8388608.
  * The function cstri_buf_to_stri has been added to striutl.c.
  * The generation of float literals in the compiler has been improved
    to avoid that precision is lost.

  Changes:

  * Errors in con_wat.c and drw-dos.c have been fixed (thanks to
    "Rugxulo" for the help to fix them).
  * The function str in duration.s7i has been improved to work for
    negative durations.

  * The macros with format strings in common.h have been renamed.
    Now the macros have shorter names (starting with FMT_ and F_).
    The macros define formats for various integer sizes. This formats
    are independend from the actual C compiler and C runtime library.
  * The function bigLog10 in big_rtl.c has been improved to work
    correctly when BIGDIGIT_SIZE is small.

  * The program chkccomp.c has been improved to write the define
    directives to the file specified with the first parameter.
  * The function intParse in int_rtl.c has been improved to accept the
    most negative number.
  * The function timSetLocalTZ in tim_rtl.c has been changed to avoid
    raising an exception when LOCALTIME_WORKS_SIGNED is not defined and
    the time is before 1970-01-01. In this case the daylight saving
    time flag is set to FALSE.

    and bigrat.s7i. It rounds halfway cases away from zero.
  * The function str has been improved in the libraries rational.s7i
    and bigrat.s7i. Now the function converts to a string with a
    decimal representation (e.g.: "1.25"). When repeating decimals are
    recognizend they are enclosed in parentheses.
  * The operator digits has been improved in the libraries rational.s7i
    and bigrat.s7i. Now the operator rounds halfway cases away from
    zero.
  * Documentation comments have been improved in bigint.s7i, float.s7i,
    rational.s7i, bigrat.s7i, char.s7i, big_gmp.c and fltlib.c.
  * Definitions of the constants integer.first and integer.last have
    been added to integer.s7i.

  Changes:
  * The chapter in the manual about the foreign function interface has
    been improved.
  * A paragraph about regular expressions and lexical scanner functions
    has been added to the FAQ.
  * The handling of the actions CHR_CLIT and INT_STRI in the compiler
    has been improved. The string buffers for chrCLitToBuffer and
    intStrToBuffer use the correct alignment now.
  * In big_rtl.c the functions bigParseBasedPow2 and bigParseBased2To36
    have been added and bigParseBased has been changed to call them.
    This improves the conversion of a string to a bigInteger, when the
    base is a power of two. Valgrind measurements of the function
    bigParseBased in chkbig.sd7 show a speed improvement with a factor
    of 239.
  * The macros memcpy_to_strelem and memset_to_strelem (defined in
    striutl.h) have been turned into functions (defined in striutl.c).
  * The unrolling in memcpy_to_strelem and memset_to_strelem has been
    changed from 8 times to 32 times. This improves the performance
    for big data amounts by 16% (Measured with valgrind and gcc).
  * Usages of the macros memcpy_to_strelem and memset_to_strelem in
    bst_rtl.c, fil_rtl.c, soc_rtl.c and str_rtl.c have been turned into
    usages of the corresponding functions.
  * Calls of cstri_expand, ustri_expand, cstri_expand2 and
    ustri_expand2 in analyze.c, chr_rtl.c, flt_rtl.c, infile.c,
    str_rtl.c and striutl.c have been turned into calls of
    memcpy_to_strelem.
  * The functions (macros) cstri_expand, ustri_expand, cstri_expand2
    and ustri_expand2 have been removed from striutl.c and striutl.h.
  * The functions doCompileAndLink, compileAndLinkWithOptionsOk,
    compileAndLinkOk, appendToFile and detemineDatabaseDefines have
    been added to chkccomp.c. The function compilationOkay has been
    replaced by compileAndLinkOk.

  * The chapters in the manual about primitive actions and the foreign
    function interface have been improved.
  * The names of the C types used in interpreter and runtime library
    have been refactored to use camel case.
  * The elements in the unions valueUnion (in data.h) and rtlValueUnion
    (in data_rtl.h and s7c.sd7) have been refactored to use names with
    camel case.
  * The library bigint.s7i has been changed to define the operators
    radix and RADIX with the actions BIG_radix and BIG_RADIX. This
    results in a significant performance improvement when large numbers
    are converted.
  * Interpreter and compiler have been improved to support the actions
    BIG_radix and BIG_RADIX.
  * Testcases for the operators radix and RADIX have been added to
    chkbig.sd7.
  * The compiler has been improved to do an optimization for the action
    INT_MDIV when the divisor is known at compile time. When the
    dividend is known to be positive or zero it is casted to an
    unsigned integer and the quotient is casted back to a signed
    integer. Dividing an unsigned integer by a constant is known to be
    faster than dividing a signed integer.
  * The functions bigRadix, bigRadixPow2, bigRadix2To36 and
    uBigDivideByDigit have been added to big_rtl.c
  * The function bigRadix has been added to big_gmp.c.
  * The functions stri_to_cstri8_buf and cstri8_buf_to_stri have been
    added to striutl.c.
  * In traceutl.c the function mapTraceFlags has been improved to work
    correctly when the parameter trace_level defines several options.
  * The function printTraceOptions has been added to traceutl.c.
  * In arr_rtl.c the definition of getArgv has been improved to use
    less #ifdef directives in the function body.

  Changes:

  * The documentation file doc/install.txt has been improved to describe
    the command 'make install'.
  * The chapter about the foreign function interface in the manual has
    been improved.
  * In striutl.h the macros os_stri_alloc and os_stri_free have been
    improved to use a stack like allocation. Allocations done with
    os_stri_alloc must be freed with os_stri_free in the reverse order
    of their creation. The new macros reduce the runtime of
    stri_to_os_stri and cp_to_os_path to 66% of the old time. This
    reduces the time used by operating system calls. E.g.: The CPU time
    used by the program sydir7 is reduced to 83% of the old time.
  * The targets 'install' and 'uninstall' have been added to makefile,
    mk_linux.mak, mk_osx.mak, mk_clang.mak, mk_cygw.mak, mk_mingw.mak,
    mk_msys.mak, mk_nmake.mak, mk_msvc.mak, mk_bcc32.mak and
    mk_bccv5.mak.
  * The program setwpath.c has been added. This program sets the search
    path (PATH variable) under Windows.
  * The obsolete target 'hi' has been removed from the makefiles.
  * The functions initEmulatedCwd, cmdSetenv (both in cmd_rtl.c),
    setEmulatedCwd (in striutl.c) and freeArgVector (in cmd_unx.c) have
    been adjusted to work with the stack like allocation of
    os_stri_alloc and os_stri_free.
  * The functions heapAllocOsStri and heapFreeOsStri have been added to
    striutl.c.
  * Usages of MAX_SYMLINK_PATH_LENGTH in cmd_rtl.c have been replaced
    with MAX_OS_STRI_LEN.

  Changes:

  * The function setSockOpt and the constant SO_REUSEADDR have been
    added to sockbase.s7i. Many thanks go to Domingo Alvarez Duarte
    for pointing out that this functionality was missing.
  * The function openInetListener in listener.s7i has been improved
    to succeed when the socket is reused (it calls setSockOpt with
    SO_REUSEADDR now).
  * The functions opendir and wopendir in dir_win.c and the function
    opendir in dir_dos.c have been improved to check for the maximum
    path length supported by Windows and DOS.
  * The functions act_string and act_okay have been removed from
    actutl.c.
  * The function exec_action in exec.c has been improved to use
    get_primact instead of act_okay. This results in a significant
    performance improvement in the case when WITH_ACTION_CHECK is
    defined and the option -tc is used.
  * The function str1Split has been removed from strlib.c.
  * Documentation comments have been added to arr_rtl.c, arrutl.c,
    cmd_unx.c, cmd_win.c, dir_dos.c, dir_rtl.c, dir_win.c, kbd_inf.c,
    kbd_poll.c, scanner.c and ut8_rtl.c.
  * Interpreter and compiler have been improved to support the action
    SOC_SET_OPT_BOOL.

- Update to 05_20140216

  Changes:

  * A new numeric escape sequence for string literals has been
    introduced. A backslash followed by an integer literal and a
    semicolon is interpreted as character with the specified ordinal
    number. E.g.: "abc\128;def". With the old numeric escape sequence
    this would be "abc\128\def". Terminating the escape sequence
    with ; instead of \ improves the readability, especially when
    escape sequences follow each other. Instead of "\8\\12\\7\8\9\\\"
    it is now possible to write "\8;\12;\7;8\9;\\" The old escape
    sequence is still supported, but it is deprecated and should not
    be used. Future versions will warn about the deprecated escape
    sequence.
  * The conversion functions 'bytes' and 'bytes2Int' in bytedata.s7c
    have been improved to support all combinations of signedness and
    endianess.
  * The functions bStriBe and bStriLe have been removed from
    bstring.s7i. The function 'bytes' in bytedata.s7c can be used as
    replacement.
  * Checks for lowestSetBit and UNSIGNED conversions with the
    functions 'bytes' and 'bytes2Int' have been added to chkint.sd7.
  * Checks for UNSIGNED conversions with the functions 'bytes' and
    'bytes2BigInt' have been added to chkbig.sd7.
  * Checks for the function rand have been added to chkset.sd7.
  * The parser has been improved to write error messages when the
    source file contains unexpected UTF-8 continuation bytes, solitary
    UTF-8 start bytes, extended control codes from the C1 set or an
    UTF-16 byte order mark.
  * In tar.s7i the functions getoct, putspc and putoct have been
    improved. The computation of the size of padding data has also
    been improved.
  * The compiler has been improved to optimize string initialisations
    with the function strZero. StrZero creates a string of arbitrary
    length with '\0;' (zero) bytes.
  * The compiler has been improved to optimize integer exponentiation
    (action INT_POW). Now the multiplication pattern is determined at
    compile time and the number of multiplications is reduced.
  * The performance of the function setCard in set_rtl.c has been
    improved by a factor of 2.5.
  * The performance of the function setRand in set_rtl.c has been
    improved by a factor of 2.3.
  * Loop unrolling inspired by Duff's device has been introduced in
    striutl.h. The unrolling is used for tight loops which copy byte
    data to Seed7 strings in fil_rtl.c, soc_rtl.c and bst_rtl.c. The
    performance improvement has been verified with gcc and valgrind.
  * The example program err.sd7, which checks compile time error
    messages, has been improved.
  * The old way to store the data of constant bigIntegers has been
    removed from compiler and runtime library.
  * The buffers used in intRadix and intRadixPow2 (file int_rtl.c) have
    been enlarged to fit for the most negative number with a base of 2.
  * In itflib.c the functions itf_cpy and itf_cpy2 have been fixed to
    work correctly, when the destination is converted from a struct to
    an interface.
  * In traceutl.c the tracing of characters has been improved in the
    functions prot_char, prot_os_stri, prot_stri_unquoted and
    prot_bstri.
  * In ut8_rtl.c the function ut8Getc has been improved to use smarter
    checks for ranges of characters.
  * The deprecated variant of the function str, which has a second
    parameter to specify a numeric base, has been removed. The
    operators radix and RADIX can be used instead.
  * Interpreter and compiler have been improved to support the new
    actions INT_BYTES_BE, INT_BYTES_LE, INT_BYTES_BE_2_INT and
    INT_BYTES_LE_2_INT. The functions intBytesBe, int_bytesBe,
    intBytesLe, int_bytesLe, intBytesBe2Int, int_bytesBe2Int,
    intBytesLe2Int and int_bytesLe2Int have been added.
  * Support for the actions BIG_CLIT, INT_TO_BSTRI_BE, INT_TO_BSTRI_LE,
    INT_BYTES_BE_2_UINT and INT_BYTES_LE_2_UINT has been removed from
    interpreter and compiler. The functions bigImport, bigCLit,
    big_clit, intToBStriBe, int_toBStriBe, intToBStriLe, int_toBStriLe,
    intBytesBe2UInt, int_bytes_be_2_uint, intBytesLe2UInt and
    int_bytes_le_2_uint have been removed.

  Changes:

    * The manual chapter describing the foreign function interface has
      been improved.
    * The handling of Unicode in the console has been improved. Cursor
      positioning and writing Unicode strings to the desired position
      works now also under Linux.
    * A strict checking of all strings, that are passed to C functions,
      has been introduced. Zero bytes and non Unicode characters in the
      original string raise the exception RANGE_ERROR now.
    * The performance of several loops in the runtime library has been
      improved. Now the loops use indices instead of pointer increments
      and they work downward towards an index of zero. This allows C
      compilers to do more optimizations (verified with gcc and
      valgrind).
    * The enumeration types signedness and endianess have been added to
      bytedata.s7c.
    * The conversion functions bytes, bytes2Int and bytes2BigInt have
      been added to bytedata.s7c. The new function allow conversions
      to and from signed and unsigned byte strings with big- and
      little-endian byte order. This functions replace the less flexible
      functions bytesLe2Int, bytesBe2Int, bytesLe and bytesBe.
    * The functions bStriBe, bStriLe, bStriBe2BigInt and bStriLe2BigInt
      have been moved from bytedata.s7c to bstring.s7i.
    * The performance of the functions int16AsTwoBytesLe,
      int32AsFourBytesLe, int64AsEightBytesLe int16AsTwoBytesBe,
      int32AsFourBytesBe and int64AsEightBytesBe has been improved.
    * Documentation comments have been added or improved in cc_conf.s7i,
      bytedata.s7i, environment.s7i, sockbase.s7i, actutl.c, big_rtl.c,
      big_gmp.c, biglib.c cmd_rtl.c, con_inf.c, con_win.c, con_wat.c,
      int_rtl.c, intlib.c, soc_rtl.c, striutl.c and syvarutl.c.
    * The program chk_all.sd7 has been improved to check several
      compiler options and to allow that the output of interpreted and
      compiled compiler differs. The difference of the generated C code
      is okay, when the execution of the compiled programs results in
      the same output.
    * The compiler (s7c) has been improved to do more optimizations for
      the action BIG_REM (operator rem).
    * The compiler has been improved to count inserted and suppressed
      range checks.
    * Interpreter, compiler and runtime library have been improved to
      allow bstrings with slices. This is used by the compiler to
      reduce the memory used for constant bstrings.
    * The compiler has been improved to store the data of constant
      bigIntegers in bstrings.
    * Checks for div, rem, mdiv and mod have been added to chkbig.sd7.
    * Checks for float division by zero have been added to chkexc.sd7.
    * Checks for float parse have been added to chkflt.sd7.
    * In con_inf.c, con_win.c and con_wat.c the function conText has
      been replaced by conWrite. ConWrite takes an UTF-32 string and
      writes it to the console. If stdout is redirected an UTF-8 string
      is written to the destination file.
    * The function gen_act_ptr_table has been added to actutl.c. This
      function creates act_ptr_table and removes double entries from it.
    * The functions intBytesBe2UInt and intBytesLe2UInt have been added
      to int_rtl.c.
    * Interpreter and compiler have been improved to support the new
      actions INT_BYTES_BE_2_UINT and INT_BYTES_LE_2_UINT.
    * Checks for the function sigaction() and for integer division and
      remainder have been added to chkccomp.c.
    * The configuration values ALLOW_BSTRITYPE_SLICES,
      CHECK_INT_REM_BY_ZERO and CHECK_INT_REM_ZERO_BY_ZERO have been
      added to cc_conf.s7i, chkccomp.c, cmd_rtl.c and s7c.sd7.
    * Several versions of timAwait in tim_unx.c have been improved to
      restart calls of poll(), ppoll() and select().
    * A check for the character '=' in the environment variable name has
      been added to the function cmdSetenv (in cmd_rtl.c).
    * In striutl.c the functions stri_compress, stri_export_utf8 and
      cp_to_cstri8 have been improved and renamed to conv_to_cstri
      conv_to_cstri8 and stri_to_cstri8 respectively. Interpreter and
      runtime library have been improved to use the new function names.
    * The function stri_to_cstri and the macro free_cstri8 have been
      added to striutl.c.
    * The functions conv_to_cstri, conv_to_cstri8, stri_to_cstri8 and
      stri_to_bstri have been improved to use an err_info parameter.

    cipher support has been added.
  * The library tls.s7i has been improved to allow encoding with TDES
    (3DES) and to accept the handshake message CertificateRequest.
  * The function drwGetImage has been added to drw_dos.c (thanks to
    "Rugxulo" for pointing out, that it was missing).
  * Checks for mdiv and mod have been added to chkbig.sd7.
  * The compiler (s7c) has been improved to do more optimizations for
    the action BIG_MOD (operator mod). Now the functions bigLowerBits
    and bigLowerBitsTemp are used when the divisor is a power of two.
  * The compiler has been improved to optimize if-statements, when the
    condition is constant.
  * The compiler has been improved to optimize the action BIG_MDIV
    (operator mdiv) correctly, when the divisor is a negated power of
    two (e.g. n div -8). The generated code now corresponds to the
    Seed7 expression -dividend >> log(-divisor).
  * New functions to open files have been introduced in various
    libraries. The new functions are openUtf8, openUtf16, openEcho,
    openLine, openTee, openMore, openUpper, openLower, openReverse,
    openWindow and openField. The new functions have been added as
    replacement for the functions open_utf8, open_utf16, open_echo,
    open_line, open_tee, open_more, open_upper, open_lower,
    open_reverse, open_window and open_field. The old functions are
    still supported, but they are deprecated and should not be used.
    Deprecated functions will be removed in a future version.
  * The example programs have been changed to use the new functions
    to open files.
  * Documentation comments have been added or improved in cipher.s7i,
    clib_file.s7i, external_file.s7i, shell.s7i, utf8.s7i, utf16.s7i,
    unicode.s7i, bytedata.s7i, big_gmp.c, biglib.c, big_rtl.c,
    cmdlib.c, cmd_rtl.c, fillib.c, fil_rtl.c, intlib.c, int_rtl.c,
    strlib.c, str_rtl.c and entutl.c.
  * The functions bigLowerBits and bigLowerBitsTemp have been added
    to big_rtl.c and big_gmp.c.
  * The free list management in big_rtl.c and big_gmp.c has been
    improved to allow the configuration of a maximum free list length.
  * The function bigMultAssign1 has been added to big_rtl.c. This
    function is used by bigMultAssign when the factor is just one
    bigdigit.
  * The function bigLog2BaseLShift has been renamed to
    bigLog2BaseIPow in big_rtl.c, big_gmp.c and s7c.sd7.
  * The function getValue for boolean values has been added to
    progs.s7i. Interpreter, compiler and runtime library have been
    improved to support it.
  * the management of types in the runtime library has been improved.

    cannot happen that a sequence like ??( is interpreted as trigraph
    sequence. As a side effect the performance has been improved also.
  * The function init_win_constants in s7c.sd7 has been improved to
    call getImage instead of getPixel. This improves the performance
    dramatically.

    from a position with maximum length, has been added to the manual.
  * A table to map keysym values to Unicode and the function
    mapKeysymToUnicode, which does a binary search in this table, have
    been added to gkb_x11.c.
  * The function gkbGetc in gkb_x11.c has been improved to work without
    recursion, to use mapKeysymToUnicode and to recognize cursor keys
    in combination with ALT, NUMLOCK and SHIFT.

  * Documentation comments have been added or improved in bigfile.s7i,
    char.s7i, clib_file.s7i, complex.s7i, external_file.s7i, file.s7i,
    float.s7i, hash.s7i, integer.s7i, shell.s7i, string.s7i, utf16.s7i,
    osfiles.s7i, rational.s7i, arrlib.c, blnlib.c, bstlib.c, arr_rtl.c,
    big_gmp.c, big_rtl.c, bst_rtl.c, chrlib.c, chr_rtl.c, cmdlib.c,

  * The functions lower and upper in string.s7i and char.s7i have been
    improved to use the default Unicode case mapping. In other words:
    conversions to lower respectively upper case works for all Unicode
    characters, which have a case mapping. Characters without case
    mapping are left unchanged. The mapping is independend from the
    locale. Individual character case mappings cannot be reversed,
    because some characters have multiple characters that map to them.
  * In the library deflate.s7i the performance of the deflate
    compression has been improved by a factor between 5 and 10.
  * The performance of the functions str_cmp, str_range and str_substr
    in strlib.c has been improved.

    HSH_UPDATE.
  * The compiler has been improved to inline code for the actions
    STR_HASHCODE, STR_RANGE and STR_SUBSTR.

    function allows conversions from integer to string, without
    memory allocation.
  * The compiler has been improved to take advantage of the function
    intStrToBuffer.
  * The functions getGenericValue, getGenericValueToResultExpr,
    getTempVariable, beginCastGeneric, endCastGeneric,
    beginCastGenericToResultExpr and endCastGenericToResultExpr have
    been added to the compiler.
  * The functions hsh_idx2 and hsh_update have been added to hshlib.c.
  * The functions hshIdxAddr2 and hshUpdate have been added to
    hsh_rtl.c
  * The macro hashCode has been defined in str_rtl.h and used in
    str_rtl.c (function strHashCode) and strlib.c (function
    str_hashcode).
  * The program chkccomp.c was improved to write a definition of the
    macro INLINE to version.h
  * The deprecated function 'read_dir' has been removed from the
    library "osfiles.s7i". The replacement of 'read_dir' is 'readDir'.
  * The functions arrHeadTemp, arrRangeTemp and arrSubarrTemp in
    arr_rtl.c have been improved.

    to the library array.s7i.
  * In seed7_05.s7i the functions hashCode and compare have been
    defined for enum types.
  * In the library bigrat.s7i the operator parse has been improved. Now
    the parse operator accepts decimal numbers with repeating decimals.

    This function converts a numeric string, with a specified radix, to
    an integer.
  * The function bigInteger has been added to the library bigint.s7i.
    This function converts a numeric string, with a specified radix, to
    a bigInteger.
  * The files encoding.s7i, gethttp.s7i, scanfile.s7i, scanstri.s7i,
    xml_ent.s7i and bas7.sd7 have been changed to use the new function
    integer instead of toInt (toInt was an undocumented internal
    function).
  * Checks for the function integer have been added to chkint.sd7.
  * Checks for the function bigInteger have been added to chkbig.sd7.
  * The operator sci has been added to to the library complex.s7i. This

    when the usage_count reaches zero.
  * The UNUSED flag was defined in data.h and used to monitor if the
    object memory can be freed.
  * The compiler has been improved to call the destructor for local
    interface objects (In process_local_declaration process_destr_call

- Update to 05_20130401
  Changes:
  - The FAQ explanations concerning, 'in' parameters and different
    behavior of val and ref parameters, have been improved.
  - The keyboard read function getc(KEYBOARD) has been improved to
    support more function keys and to accept Unicode characters also
    under Windows.
  - The program calc.sd7 has been improved to accept and display
    Unicode characters.
  - The automatic memory management has been improved to work also
    for the files managed by pollData.
  - The function openEditLineLatin1 has been added to editline.s7i.
    Only Latin-1 characters are accepted and written to ''outFile''.
    Unicode characters beyond ISO Latin-1 (ISO-8859-1) are ignored.
  - In file.s7i the function writeln(file, string) has been defined as
    DYNAMIC (virtual) function. This allows that the implementation
    function writeln(socket, string) sends string and '\n' together.
  - The definition of keys in keybd.s7i have been changed such that
    function keys are outside the range of Unicode characters.
  - The new library keydescr.s7i, which defines a hash table with
    descriptive text for function keys, has been added.
  - The implementation function writeln(null_file, string) has been
    added to null_file.s7i. This function is used by many derived
    types.
  - An implementation function of writeln(socket, string) has been
    added to socket.s7i. This function sends string and '\n' together.
  - Definitions of writeln (without string parameter) have been removed
    from external_file.s7i, socket.s7i and utf8.s7i.
  - The example programs bas7.sd7, gkbd.sd7 and kbd.sd7 have been
    changed to use the hash keyDescription (defined in keydescr.s7i).
  - Tests for string assignment and string append (operator &:= ) have
    been added to chkstr.sd7.
  - The function bigStr in big_rtl.c has been improved to realloc the
    string to the correct size.
  - The function determineEnvironDefines in chkccomp.c has been
    improved.
  - The function itf_destr in itflib.c has been improved to cooperate
    with the function close_stack (defined in name.c).
  - The function kbdKeyPressed in kbd_inf.c has been improved to never
    wait for input (calls of tcsetattr() were fixed, see below).
  - In pol_unx.c and pol_sel.c the functions addCheck, removeCheck,
    polCpy, polCreate, polDestr and polClear have been improved to use
    the function pointers incrUsageCount and decrUsageCount from
    fileObjectOps.
  - The function initPollOperations has been added to pol_unx.c,
    pol_sel.c and pol_dos.c.
  - In str_rtl.c the functions strAppend and strCopy have been changed
    to use SLICE_OVERLAPPING instead of GET_SLICE_ORIGIN.
  - In str_rtl.c the functions strHeadSlice, strRangeSlice,
    strSubstrSlice and strTailSlice have been improved to avoid
    (mis)using the string capacity. Now the capacity of a slice is set
    to zero. Before the origin of a slice was stored in the capacity.
  - The function print_real_value in traceutl.c has been improved to
    print interface values with more detail.
  - Support for additional function keys has been added to kbd_inf.c,
    kbd_poll.c, cap_def.h, trm_cap.c and trm_inf.c.
  - The files kbd_inf.c and kbd_poll.c have been improved to use read()
    instead of fread().
  - The files kbd_inf.c and kbd_poll.c have been improved to take a
    weakness of tcsetattr() into account. The function tcsetattr() may
    return success, although not all changes could be carried out.
    Now the calls of tcsetattr() are done via the new functions
    term_descr_equal, tcset_term_descr and tcset_vmin_vtime.
  - The compiler has been improved to create and use cpy_... functions
    for the interface assignment (action ITF_CPY).
  - The free list management for strings has been improved to allow
    different maximum list lengths for strings with different capacity.
  - Definitions of databasetype and sqlstmttype have been added to
    common.h. This are the first steps towards database support.
