That should cover all the possibilities. I like it.

Hi Scott.

Perhaps the attached patch is the "right way" to identify int64_t presence?
The problem of that approach is that, in architectures missing
stdint.h, HAVE_INT64_T would not be defined but a suitable int64_t
would be provided by gnulib.

To cover those cases, and since the gnulib stdint.h is always
#defining int64_t, I would also check for int64_t:

  -#if defined(int64_t) && !defined(PDF_FORCE_BIGNUMS)
  +/* Note that int64_t may be defined by the gnulib stdint.h in
  +   platforms missing that header file. */
  +#if (defined(HAVE_INT64_T) || defined(int64_t)) &&
!defined(PDF_FORCE_BIGNUMS)

#define PDF_USE_BUILTIN_64BIT_SUPPORT #endif
What do you think?
