//  MACRO:         BOOST_HAS_MACRO_USE_FACET
//  TITLE:         macro version of use_facet: _USE
//  DESCRIPTION:   The standard library lacks a conforming std::use_facet,
//                 but has a macro _USE(loc, Type) that does the job.
//                 This is primarily for the Dinkumware std lib.

#error "macro _USE not defined"
