That's interesting.  The original <inttypes.h> proposal for C99 had
everything in one header; it was later divided up between <stdint.h>,
which is required for all implementations, and <inttypes.h>, which is
only required for hosted implementations and includes <stdint.h> so that
code that only included <inttypes.h> would continue to work.

Given that history, I would expect any implementation of <inttypes.h> to
either define all the <stdint.h> stuff itself (which is what the SGI
version does in C89 mode) or #include <stdint.h> (which is what it does
in C99 mode).  I can't imagine why any implementation would have split
the stuff up without doing the appropriate #include to protect existing
code.
