The ATLAS (Automatically Tuned Linear Algebra Software) project is
an ongoing research effort focusing on applying empirical techniques
in order to provide portable performance.
At present, it provides C and Fortran77 interfaces to a
portably efficient BLAS implementation, as well as a few routines from LAPACK.
If you use blas, you can simply change flags when linking,
from -lblas to -lf77blas -latlas (order is important).
A few routines from LAPACK are merged into one library as libalapack.
It requres both C and Fortran77 interfaces, and thus that link line would be:
-lalapack -lf77blas -lcblas -latlas -lg2c -lm .
Other choice of CC and CFLAGS are *NOT* recommended.
They are already optimized for this platform and automatically searched.

Repair instances, almost all courtesy of bf ;-), of spaces
and/or tabs before the =. This made doing regular expressions
on the ports tree really difficult.

Fixup for USES=fortran conversion. These ports require USE_GCC=yes
because they depend on gcc specific optimisation flags.
While here use USES=tar:bzip2.

Update the default version of GCC used in the Ports Collection from
GCC 4.6.4 to GCC 4.7.3. This entails updating the lang/gcc port as
well as changing the default in Mk/bsd.default-versions.mk.
Part II, Bump PORTREVISIONs.
PR: 182136
Supported by: Christoph Moench-Tegeder <cmt@burggraben.net> (fixing many ports)
Tested by: bdrewery (two -exp runs)
Convert all USE_FORTRAN=yes to "USES=fortran, USE_GCC=yes". In most cases
USE_GCC=yes has been omitted though.
Remove USE_FORTRAN handling from bsd.port.mk and bsd.gcc.mk.
Minor cleanups in some ports like USE_GMAKE, NOPORTDOCS,...

Update to libmpc version 1.0.1 which brings the following fixes:
- Switched to automake 1.11.6, see CVE-2012-3386.
- #14669: Fixed extraction of CC from gmp.h.
- Fixed case of intermediate zero real or imaginary part in mpc_fma,
found by hydra with GMP_CHECK_RANDOMIZE=1346362345.
This is on top of the following changes from version 1.0
- Licence change towards LGPLv3+ for the code and GFDLv1.3+ (with no
invariant sections) for the documentation.
- 100% of all lines are covered by tests
- Renamed functions
. mpc_mul_2exp to mpc_mul_2ui
. mpc_div_2exp to mpc_div_2ui

In ATLAS/INSTALL.txt it is said that gcc42 is superior to both gcc3 and gcc41
- and FreeBSD 7 current imported gcc42.

o Do not build static libraries in default setting; this reduce the
build time by half.
o Add support for Pentium D
o timing_torerance patch is now activated via knob; this significantly
reduce the build time.
A lot of discussion with: "Pedro F. Giffuni" <giffunip@yahoo.com>
Currently with "cpu I686_CPU" which is default,
kernel automatically enables SSE if it is available.
so remove messages which are not necessary.

Add two patches for stable builds.
o L1 cache size is not correctly detected having a bad clock
o in some case small number of tries in tuning doesn't meet convergence

Backout previous change of PICFLAG, since
behaviour of -fPIC and -fpic are different.
Here is the comment form obrien:
--
"-fpic" is a [minor?] optimization for machines that can handle it:
-fpic
Generate position-independent code (PIC) suitable for use in a shared
library, if supported for the target machine. Such code accesses all
constant addresses through a global offset table (GOT). The dynamic
loader resolves the GOT entries when the program starts (the dynamic
loader is not part of GCC; it is part of the operating system). If
the GOT size for the linked executable exceeds a machine-specific
maximum size, you get an error message from the linker indicating
