When gnulib is configured in C++ mode for a system with a working C99
implementation of stdint.h that predates C++11, gnulib ends up
substituting stdint.h anyway. This works on most targets, but on e.g.,
64-bit MinGW, it doesn't, as gnulib's substitute assumes LP64, while
MinGW is LLP64. Instead of trying to detect the right types, detect
good-enough-pre-C++11 stdint.h and in such case define
__STDC_CONSTANT_MACROS/__STDC_LIMIT_MACROS in config.h.
* m4/stdint.m4 (gl_STDINT_H): Always define __STDC_CONSTANT_MACROS
/ __STDC_LIMIT_MACROS while checking whether the system stdint.h
conforms to C99. If it does, check whether it hides symbols
behind the __STDC_{CONSTANT|LIMIT}_MACROS macros. Then if it
does, define those macros in config.h.

Problem reported for glibc 2.14 and g++ by Alexander V. Lukyanov in
<http://lists.gnu.org/archive/html/bug-gnulib/2011-12/msg00099.html>.
* m4/stdint.m4 (gl_STDINT_H): Don't go to extra work to make it
work also in C++ before C++11, as that improperly inhibits
generating a substitute stdint.h for that case.
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.

* tests/test-inttypes.c (__STDC_LIMIT_MACROS, __STDC_CONSTANT_MACROS)

Likewise.

I noticed this while updating libvirt to the latest gnulib.

This reverts part of a 2007-01-06 commit. Reported by Paul Eggert.
* lib/intprops.h (TYPE_MINIMUM, TYPE_MAXIMUM): Do not shift a
negative number, which the C Standard says has undefined behavior.
In practice this is not a problem, but might as well do it by the book.
Reported by Rich Felker and Eric Blake; see

99% of this change was performed by running the following commands:
git ls-files | grep '\.m4$' | xargs perl -pi \
-e 's/(AC_\w+\()([^[()]+?)([,)])/$1\[$2]$3/g;' \
-e 's/(AC_\w+\((?:\[[^,]+?\], ){1})([^,[()]+?)([,)])/$1\[$2]$3/g;' \
-e 's/(AC_\w+\((?:\[[^,]+?\], ){2})([^,[()]+?)([,)])/$1\[$2]$3/g;' \
-e 's/(AC_\w+\((?:\[[^,]+?\], ){3})([^,[()]+?)([,)])/$1\[$2]$3/g'
perl -pi -e 's/\[\.\.\.\]/.../' m4/onceonly.m4
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

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.
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.
