  vasnwprintf-posix: Fix behaviour in the C locale.
  
  * lib/vasnprintf.c (VASNPRINTF): If NEED_WPRINTF_DIRECTIVE_C is set,
  implement the 'c' directive here.
  * m4/vasnprintf.m4 (gl_PREREQ_VASNWPRINTF): Invoke gl_MBRTOWC_C_LOCALE.
  If mbrtowc is buggy in the C locale, define NEED_WPRINTF_DIRECTIVE_C.
  * modules/vasnwprintf (Files): Add m4/mbrtowc.m4.
  * tests/test-vasnwprintf-posix.c (test_function): Add tests of %s and %c
  in the C locale.
  * doc/posix-functions/fwprintf.texi: Mention the C locale behaviour bug.
  * doc/posix-functions/swprintf.texi: Likewise.
  * doc/posix-functions/vfwprintf.texi: Likewise.
  * doc/posix-functions/vswprintf.texi: Likewise.
  * doc/posix-functions/vwprintf.texi: Likewise.
  * doc/posix-functions/wprintf.texi: Likewise.

  Portability problems not fixed by Gnulib:
  @itemize
  @item
  This function is missing on some platforms:
  NetBSD 3.0, OpenBSD 3.8, Minix 3.1.8, HP-UX 11.00, IRIX 6.5, Cygwin 1.5.x.
  @item
  On Windows and 32-bit AIX platforms, @code{wchar_t} is a 16-bit type and therefore cannot
  accommodate all Unicode characters.
  @item
  This function does not support size specifiers as in C23 (@code{w8},
  @code{w16}, @code{w32}, @code{w64}, @code{wf8}, @code{wf16}, @code{wf32},
  @code{wf64}) on some platforms:
  glibc, musl libc, macOS 12.5, FreeBSD 13.1, NetBSD 9.0, OpenBSD 7.2,
  AIX 7.2, HP-UX 11, Solaris 11.4, Cygwin 2.9.0, mingw, MSVC 14.
  @item
  This function does not support the @samp{b} directive, required by ISO C23,
  on some platforms:
  glibc 2.34, musl libc, macOS 12.5, FreeBSD 13.1, NetBSD 9.0, OpenBSD 7.2,
  AIX 7.2, HP-UX 11, Solaris 11.4, Cygwin 2.9.0, mingw, MSVC 14.
  @item
  The @code{%m} directive is not portable, use @code{%s} mapped to an
  argument of @code{strerror(errno)} (or a version of @code{strerror_r})
  instead.
  @item
  In the C or POSIX locales, the @code{%c} and @code{%s} conversions may fail
  on some platforms:
  glibc 2.35.
  @item
  When formatting an integer with grouping flag, this function inserts thousands
  separators even in the "C" locale on some platforms:
  NetBSD 5.1.
  @item
  On some platforms, this function does not set @code{errno} or the
  stream error indicator on attempts to write to a read-only stream:
  Cygwin 1.7.9.
