//  MACRO:         BOOST_NO_CWCTYPE
//  TITLE:         <wctype.h> and <cwctype>
//  DESCRIPTION:   The Platform does not provide <wctype.h> and <cwctype>.

//
// Note that some platforms put these prototypes in the wrong headers,
// we have to include pretty well all the string headers on the chance that
// one of them will contain what we want!

#include <cwchar>
#include <wchar.h>
#include <cctype>
