7087	std::forward or std::move missing in Boost.Test on Darwin Clang	Paul A. Bristow	Gennadiy Rozental	"Sandia-darwin-clang compiler in

../boost/test/tools/assertion.hpp

seems to be missing something for several Boost.math tests, for example:

Sandia-darwin-clang-trunk-c++11 - math - hypot_test / clang-darwin-trunk

../boost/test/tools/assertion.hpp:278:29: error: 'T' does not refer to a value
    : m_value( std::forward<T>(val) )
                            ^

../boost/test/tools/assertion.hpp:386:36: error: no member named 'forward' in namespace 'std'
        return value_expr<T>( std::forward<T>( v ) );

Could be a missing #include, or else the compiler has rvalue refs but no std::move/forward?
