Re: verify fails on ia64-hpux11.23 in libunistring-0.9.3

So, the problem is that TYPE_MAXIMUM (uint_fast8_t)
expands to 2**32 - 1, whereas it should expand to
2**64 - 1.  Can you use cc -E to find what expression
TYPE_MAXIMUM (uint_fast8_t) expands to, and
investigate why that expansion evaluates to the
wrong value?  My impression is that TYPE_MAXIMUM (uint_fast8_t)
should expand to (unsigned long) -1, which should be
2**64 - 1 on ia64-hpux11.23, but evidently that is not happening
correctly.  Perhaps it's a compiler bug?
