Are you sure you're looking at a C90 draft and not a C99 draft?

The draft linked from the Wikipedia page:

    http://flash-gordon.me.uk/ansi.c.txt

doesn't mention <inttypes.h> or the PRIxPTR define.  I'm fairly sure
they're not part of C90, since the uintptr_t typedef isn't either.

Actually, I think their defenition is ok (but nonstandard).  IIRC,
%I64x is the way to print the __int64 type that Microsoft invented
before long long was standardized by C99.  So it seems the problem
here is with gcc.

I'll reply to your origional mail to discuss your alternative suggestions.
