Success with cegcc on MacOS X 10.9

This post has NOT been accepted by the mailing list yet.
FYI, I successfully compiled both cegcc and mingw32ce (and support libraries) on a recent MacOSX (10.9.2) by just applying this small patch.  There's something with the LLVM-backed c compiler that is different so we get multiple definitions. I'm just posting this here so people can search for it, as I pressume that cegcc is not being actively maintained.
