Port to Tandem NSK OSS, which has 64-bit signed int but at most 32-bit unsigned int. Problem reported by Matthew Woehlke in: http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00062.html More generally, don't assume that 64-bit signed int is available if unsigned int is, and vice versa. * lib/inttypes_.h (_PRIu64_PREFIX, _SCNu64_PREFIX): Depend on unsigned symbols, not on their signed counterparts. * lib/stdint_.h (uint64_t, uint_least64_t, uint_fast64_t, uintmax_t): (UINT64_MAX, UINT_LEAST64_MAX, UINT_FAST64_MAX, UINTMAX_MAX): (UINT64_C, UINTMAX_C): Likewise. * lib/strtoimax.c (strtoll): Depend on signed symbols, not their unsigned counterparts. (Have_long_long, Unsigned): New macros. (Int): Renamed from INT. (strtoimax): Use the new macros. * m4/stdint.m4 (gl_STDINT_H): Require AC_TYPE_UNSIGNED_LONG_LONG_INT and substitute HAVE_UNSIGNED_LONG_LONG_INT. * modules/inttypes (inttypes.h): Substitute HAVE_UNSIGNED_LONG_LONG_INT. * modules/stdint (stdint.h): Likewise. (Files): Add m4/ulonglong.m4.
