On the other side, glibc is the de facto standard. I see the following 
in /usr/include/wchar.h in my Linux:

/* The X/Open standard demands that most of the functions defined in
   the <wctype.h> header must also appear here.  This is probably
   because some X/Open members wrote their implementation before the
   ISO C standard was published and introduced the better solution.
   We have to provide these definitions for compliance reasons but we
   do this nonsense only if really necessary.  */
#if defined __USE_UNIX98 && !defined __USE_GNU
# define __need_iswxxx
# include <wctype.h>
#endif

In newer glibc versions, that paragraph is still present but it moved to 
wcsmbs/wchar.h:
https://sourceware.org/git/?p=glibc.git;a=blob;f=wcsmbs/wchar.h;hb=HEAD

Another example, on Newlib (used by Cygwin), wchar.h does not include 
wctype.h at all :
https://sourceware.org/cgi-bin/cvsweb.cgi/src/newlib/libc/include/wchar.h?rev=1.31&content-type=text/x-cvsweb-markup&cvsroot=src

I'm not sure of how that stuff translates to the MiNT world...
