//  MACRO:         BOOST_NO_CXX11_CHAR32_T
//  TITLE:         C++0x char32_t unavailable
//  DESCRIPTION:   The compiler does not support C++0x char32_t

namespace boost_no_cxx11_char32_t {

//  Microsoft VC++ 2010, and possibly other compilers, provides
//  a typedef for char32_t rather than a new type. We want that
//  to be an error, so provide an overloaded function that will
//  be ambiguous if char16_t is just a typedef.
