To clarify this to avoid unnecessary confusion: there are two different
interfaces that deal with character classification, ctype.h and
wctype.h. I am only talking about ctype.h and the necessary 257 entry
table used by the macros in it. This is not about wchar_t and the
associated issues like dynamic character classes etc.
