1) -- F2C --
The F2C (from http://www.netlib.org/f2c, both libf2c.a and the executable)
passes compilation on GCC 4.1.2 (that I have) without even one warning,
simply by typing "GNUmake -f makefile.u".
You can add -fPIC option and produce shared library.

2)  -- Your special libs --
If you can compile and use your "special" C code on GCC, then you can work
on any platform GCC is installed on. Otherwise you will be bound to
Visual Studio,
of which I have little knowledge. MinGW project should ensure interoperability
with libraries compiled on Visual Studio. DJGPP (http://www.delorie.com/djgpp/)
should too... Last time I compiled anything on Windows was in 2004, I had to :)
