 FYI, for MIPS platforms you can select between 32-bit and 64-bit ints
with a compiler option.  It probably only makes sense for MIPS64*/Linux if
at all, and 64-bit ints are non-default and detectable with the
_MIPS_SZINT macro. 

 Anyway, <stdint.h> is probably the right header to get types of fixed
sizes.  Unfortunately, it's part of glibc rather than gcc, for a reason
unknown to me, at least with gcc 2.95.
