//  MACRO:         BOOST_NO_INTRINSIC_WCHAR_T
//  TITLE:         intrinsic wchar_t
//  DESCRIPTION:   The C++ implementation does not provide wchar_t,
//                 or it is really a synonym for another integral type.
//                 Use this symbol to decide whether it is appropriate
//                 to explicitly specialize a template on wchar_t if there
//                 is already a specialization for other integer types.
