That's an interesting proposal, but there are other problems on
Solaris 2.5.1 -- e.g., wchar.h and wctype.h define macros like ISPRINT
that disagree with fnmatch.c's.  (This violates the standard, but most
likely those .h files predate the standard.)  So fixing the problem
would involve more than just btowc.

These older systems are not that widely used any more, and they are
less important than adding proper support for multibyte characters on
modern systems.  If someone would volunteer to support them, that
would be fine; but there are higher-priority areas for me right now.

If we hack on a substitute btowc and fix the other problems, we merely
fix diff's -x option on Solaris 2.5.1 with multibyte characters.  But
currently, diff's -i, -E, -b, -w, -B, -I, -t, and some other options
don't work with multibyte characters even on modern hosts.  These are
the higher priority items.
