* doc/posix-headers/stdint.texi: Document this.
* lib/stdint.in.h: Add support for INTMAX_WIDTH. etc.
* m4/stdint.m4 (gl_STDINT_H): Require gl_LIMITS_H. Check for
support for INTMAX_WIDTH, etc. as well as for support for just C99.
* modules/stdint (Depends-on): Add limits-h.
(Makefile.am): Substitute HAVE_C99_STDINT_H.
* modules/stdint-tests (Depends-on): Add extensions, so that
INTMAX_MAX etc. are defined.
* tests/test-stdint.c: Verify the new macros.
More platforms have similar bugs, and in the case of glibc on s390,
the bug is in SIZE_MAX instead of SSIZE_MAX.

C++11 says there's no need to define __STDC_CONSTANT_MACROS etc.
when including inttypes.h and stdint.h. Support this change to
the standard.
* doc/posix-headers/inttypes.texi (inttypes.h):
* doc/posix-headers/stdint.texi (stdint.h): Document this.
* lib/inttypes.in.h (__STDC_FORMAT_MACROS) [! __cplusplus]:
Define if not defined already, for the benefit of pre-C++11 hosts.
Define the standard format macros (e.g., PRId8) always.
* lib/stdint.in.h (__STDC_CONSTANT_MACROS, __STDC_LIMIT_MACROS):
Likewise, if __cpluspus. Define the standard constant and limit
macros (e.g., INT8_C, INT8_MAX) always.
* m4/inttypes.m4 (gl_INTTYPES_INCOMPLETE): Do not define
GL_TRIGGER_STDC_LIMIT_MACROS or __STDC_LIMIT_MACROS; no longer needed.
* m4/stdint.m4 (gl_STDINT_H): Update comments about these macros.
* tests/test-inttypes.c (__STDC_LIMIT_MACROS, __STDC_CONSTANT_MACROS)
(__STDC_FORMAT_MACROS): Do not define, since we assume C++11 API now.
* tests/test-stdint.c (__STDC_LIMIT_MACROS, __STDC_CONSTANT_MACROS):
Likewise.
