I have a fix for darwin but I have not applied it yet, I have been
just to busy to finish it up as the C99 math functions are in the
libmx library which causes so much problems.  I have already fixed
libgfortran to support this library but I need to add support for
libstdc++.

I am almost ready to file a bug (with Apple) asking for the
functions to be in libm or libsystem as that makes it more
consistent with the rest of the UNIX world.
