  wctype-h: Work around iswprint bug on mingw.
  
  * lib/wctype.in.h (rpl_iswprint): On mingw, don't use the system's
  iswprint function.
  * tests/test-wctype-h.c (main): Verify that this character class
  contains the ASCII space but not tab and newline.
  * tests/test-c32isprint.c (main): For tab, \v, \f, expect the same value
  on native Windows as on other platforms.
  * doc/posix-functions/iswprint.texi: Mention the mingw bug.

  Portability problems fixed by Gnulib:
  @itemize
  @item
  This function is missing on some platforms:
  Minix 3.1.8.
  @item
  This function cannot be called from plain inline or extern inline functions
  on some platforms:
  OS X 10.8.
  @item
  This function returns true for the tab (@code{'\t'}) character
  on some platforms:
  mingw.

  Portability problems not fixed by Gnulib:
  @itemize
  @item
  On Windows and 32-bit AIX platforms, @code{wchar_t} is a 16-bit type and
  therefore cannot accommodate all Unicode characters.
  However, the Gnulib function @code{c32isprint}, provided by Gnulib module
  @code{c32isprint}, operates on 32-bit wide characters and therefore does not
  have this limitation.
  @end itemize
