  wctype-h: When overriding wint_t, override also the related functions.
  
  Reported by Christian Biesinger <cbiesinger@google.com> in
  <https://lists.gnu.org/archive/html/bug-gnulib/2019-11/msg00027.html>.
  
  * m4/wctype_h.m4 (gl_WCTYPE_H): When GNULIB_OVERRIDES_WINT_T is 1, set
  REPLACE_ISWCNTRL to 1.
  * lib/wctype.in.h (rpl_iswalnum, rpl_iswalpha, rpl_iswblank,
  rpl_iswcntrl, rpl_iswdigit, rpl_iswgraph, rpl_iswlower, rpl_iswprint,
  rpl_iswpunct, rpl_iswspace, rpl_iswupper, rpl_iswxdigit, rpl_towlower,
  rpl_towupper): New definitions when GNULIB_OVERRIDES_WINT_T is 1.
  * doc/posix-headers/wchar.texi: Mention that wint_t is also overridden
  on mingw.
  * doc/posix-headers/wctype.texi: Likewise.

  Portability problems fixed by Gnulib:
  @itemize
  @item
  This header file cannot be included on some platforms:
  Linux uClibc built without wide character support.
  @item
  The type @code{wint_t} is incorrect on some platforms:
  mingw, MSVC 14.
  
  @item
  Some platforms provide a @code{NULL} macro that cannot be used in arbitrary
  expressions:
  NetBSD 5.0

  Portability problems not fixed by Gnulib:
  @itemize
  @item
  This header file leads to link errors and endless recursions or endless loops
  on some platforms:
  glibc version 2.5 or older, together with gcc version 4.3 or newer and the
  option @samp{-std=c99} or @samp{-std=gnu99}.
