That part is fixed, but now mbchar.h is pulling in <wchar.h> prior to the
fixed <wctype.h>.  At this point, I really think it is easier to generate
a replacement <wchar.h> that takes care of the intricacies, then simplify
all other modules that depend on wchar.h to assume it just works, rather
than fixing all 10 occurrences of the BSD/OS workaround currently in
gnulib/lib/*.  Also, there are 8 files in lib/* that check HAVE_WCHAR_H -
is there really a modern platform that lacks this header?  If so,
providing a replacement <wchar.h> will also fix those cases, and justify
my efforts more so than making an obsolete platform work.
