I'll second that.  Very few full C99 environments actually exist yet.
I just now ran into a bug with Sun's current compiler; it mishandles
wider-than-32-bit integers in preprocessor expressions when it is
running on 32-bit sparc, because the compiler doesn't support that
part of C99 correctly yet.  GCC doesn't claim full C99 support yet
