Surely the '#include "intprops.h"' is unnecessary in the
above example, since 'main' uses only symbols that are
defined by stdint.h.  However, it may be that '#include
<stdio.h>' is needed for proper operation.  Could you
try that test again, without intprops.h, but with
stdio.h?

Which include file in HP-UX defines UINT_FAST8_MAX?  Perhaps
that include file is clashing with gnulib's stdint.h.  For
example, it could be that <limits.h> (which intprops.h includes)
redefines UINT_FAST8_MAX to the wrong value.

Also, which include file in HP-UX defines uint_fast8_t,
and what does it define it to?
