// 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.
#include <locale>
#ifndef _USE
#error "macro _USE not defined"
