indeed; missed that in my cut and pasting.

I originally had these defined to LONG_LONG_MAX and ULONG_LONG_MAX
which it (HP-UX 11.11) has. It's also got SSIZE_MAX but not SIZE_MAX,
so I originally had
#if !defined(SIZE_MAX) && defined(SSIZE_MAX) && (SSIZE_MAX == LONG_MAX)
# define SIZE_MAX ULONG_MAX
#endif
which would work in macros, but I changed it at the last minute to use
those other macros since it seemed more likely to work on any other
systems that had this problem.

Good judgement comes with experience. Unfortunately, the experience
usually comes from bad judgement.
