Comment (by gereon.kremer@…):

 Okay, then I'll wait for 1.59 and see if it vanishes. As of 1.58 (with
 clang 3.6.2 and -Wall) and the following input, I still get this "unused
 typedef" warning:

 {{{#!cpp
 #include <boost/concept_check.hpp>
 template<typename T, typename TT>
 void require_type(const TT& tt) {
     T t = tt;
     (void)(t);
 }
 template<typename T1>
 struct UnaryMinus {
     T1 t;
     BOOST_CONCEPT_USAGE(UnaryMinus) { require_type<T1>(-t); }
 };
 int main() {
     BOOST_CONCEPT_ASSERT((UnaryMinus<int>));
 }
 }}}
