Problem reported by Daniel Richard G. in
<http://lists.gnu.org/archive/html/bug-gnulib/2013-10/msg00023.html>.
* lib/inttypes.in.h (strtoumax): Replace strtoumax if
REPLACE_STRTOUMAX, thus treating it consistently with strtoimax.
* m4/inttypes.m4 (gl_INTTYPES_H_DEFAULTS): Add default for
REPLACE_STRTOUMAX.
* m4/strtoimax.m4 (gl_FUNC_STRTOIMAX):
* m4/strtoumax.m4 (gl_FUNC_STRTOUMAX):
Replace the function if defined as a macro but not as a function.
* modules/inttypes-incomplete (inttypes.h): Substitute
REPLACE_STRTOUMAX.
* modules/strtoumax (configure.ac): Replace strtoumax if
REPLACE_STRTOUMAX.
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.
I noticed this while updating libvirt to the latest gnulib.

Each *.in.h file serves two purposes - provide enough self-contained
content to serve as a replacement for the system header regardless of
the user's compiler, and offer the developer the ability to detect any
gnulib modules that might have been inadvertantly excluded. The
former requires independence from config.h, and routes everything
through a Makefile.am snippet that uses @@ substitution specific to
the modules that were in use, with details learned at configure time.
The latter works by poisoning anything that gnulib did not replace,
but which the developer had natively available, explaining why their
tests passed during development. Poisoning relies on gcc features,
and requires manual triggering by adding -DGNULIB_POSIXCHECK to
CFLAGS; it assumes that <config.h> is properly included. In fact, we
do not want to use @@ substitution for HAVE_DECL_* during poisoning,
because the warning is only relevant for the gnulib modules which were
not included, and thus where the m4 macros to set proper @@ values
have not been run. Furthermore, we only need to poison interfaces
that already have a declaration; if something is not declared, then
the developer wouldn't have been able to link, so their code won't be
using the problematic interface in the first place.

99% of this change was performed by running the following commands:

The remainder were to add Copyright dates, increment serial numbers,
undo some changes in comments, exclude m4/intl.m4, and add quotes
around the "1" in ",1" where the unusual spacing prohibited the
above regexps from doing the job. For more details, see
<http://thread.gmane.org/gmane.comp.lib.gnulib.bugs/16175>.
breaks too many things. For example, PRIdMAX still uses a 'long
long int' format with the latest Sun compiler, even though
HAVE_LONG_LONG_INT isn't defined due to that compiler's
preprocessor problem. This causes the latest coreutils to dump
core on Solaris 10 sparc with the Sun C compiler.
Instead, fix the 2007-10-16 problem in a different way, by evaluating
the troublesome expressions at configure-time, not at #if-time.
* m4/longlong.m4 (_AC_TYPE_LONG_LONG_SNIPPET): Don't test the
preprocessor.
* m4/inttypes.m4 (gl_INTTYPES_H): Move the #if checks into
compile-time C checks, done at 'configure'-time.
(gl_INTTYPES_CHECK_LONG_LONG_INT_CONDITION): New macro.
* modules/inttypes (Makefile): Substitute the new symbols that
gl_INTTYPES_H now generates.
* lib/inttypes.in.h: Don't use constants wider than 'long' in #if.
Include @ABSOLUTE_INTTYPES_H@ if available, but do nothing else.
* lib/stdint_.h (_GL_JUST_INCLUDE_ABSOLUTE_INTTYPES_H): Define
just before including <inttypes.h>, to avoid circular inclusion.
* m4/inttypes.m4 (gl_INTTYPES_H): Move ABSOLUTE_INTTYPES_H code here...
* m4/stdint.m4 (gl_STDINT_H): ... from here. This undoes the most recent
change to stdint.m4, since we're now addressing the problem in a
different way.
* modules/stdint (Makefile.am): Do not substitute ABSOLUTE_INTTYPES_H.
(jm_AC_HEADER_INTTYPES_H): Remove; now done by autoconf in 2.52.
All uses removed.
(jm_AC_TYPE_INTMAX_T, jm_AC_TYPE_UINTMAX_T):
Move AC_REQUIRE to next-to-top level, to avoid confusion.
Use 2.52's AC_CHECK_TYPE instead of merely looking for the header.
