/***
*wctype - Function versions of wctype macros
*
*Purpose:
*       Function versions of the wide char macros in ctype.h,
*       including isleadbyte and iswascii.  In order to define
*       these, we use a trick -- we undefine the macro so we can use the
*       name in the function declaration, then re-include the file so
*       we can use the macro in the definition part.
*
*       Functions defined:
*           iswalpha    iswupper     iswlower
*           iswdigit    iswxdigit    iswspace
*           iswpunct    iswalnum     iswprint
*           iswgraph    iswctrl      iswascii
*                                    isleadbyte
*
*Entry:
*       wchar_t c = character to be tested
*Exit:
*       returns non-zero = character is of the requested type
*                  0 = character is NOT of the requested type
*
*Exceptions:
*       None.
