  inttypes, stdint: add C++11 support
  
  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.

  This header file is very incomplete on some platforms.

  The PRI* macros are defined to non-string values on AIX 4.3.3.

  The declarations of @code{imaxabs} and @code{imaxdiv} are missing on some
  platforms:
  NetBSD 3.0, OpenBSD 3.8, AIX 5.1, HP-UX 11, IRIX 6.5, OSF/1 5.1, BeOS.
  @item
  The declarations of @code{strtoimax} and @code{strtoumax} are missing on some
  platforms:
  OpenBSD 3.8, AIX 4.3.2, AIX 5.1 (missing only @code{strtoumax}), OSF/1 5.1.
  @item
  On some hosts that predate C++11, when using C++ one must define
  @code{__STDC_FORMAT_MACROS} to make visible the declarations of format
  macros such as @code{PRIdMAX}.
