//  MACRO:         BOOST_NO_CTYPE_FUNCTIONS
//  TITLE:         functions in <ctype.h>
//  DESCRIPTION:   The Platform does not provide functions for the character-
//                 classifying operations in <ctype.h>. Some platforms provide
//                 macros and don't provide functions. Under C++ it's an error
//                 to provide the macros at all, but that's a separate issue.

#include <ctype.h>
