Cleanup a little (to WARNS=2 level). Declare all but the two exported
symbols as static. Add defines to allow compile against MSDB-oriented
flavour of freetds (as installed by databases/freetds-msdblib). The
default remains to depend on Sybase-using databases/freetds, but if
it is the freetds-msdblib that is actually installed at build-time, we
should now build against it properly.
This is Sybtcl -- a dynamicly loadable TCL extension, which provides
your interpreter with connectivity to a Sybase server. Althghough it was
written to work with Sybase's own client libraries (not available for
FreeBSD), this port patches it enough to make it work with FreeTDS.
