  Portability problems fixed by Gnulib:
  @itemize
  @item
  This function is missing on some platforms:
  IRIX 5.3, Solaris 2.5.1.
  @end itemize
  
  Portability problems not fixed by Gnulib:
  @itemize
  @item
  On AIX and Windows platforms, @code{wchar_t} is a 16-bit type and therefore cannot
  accommodate all Unicode characters.
  @end itemize
  
  Note: @code{wcscpy (dst, src)} is only safe to use when you can guarantee that
  there are at least @code{wcslen (src) + 1} wide characters allocated at
  @code{dst}.
