These are not going to go away unless either:
1. they are marked as expected
2. the test is reworked to avoid the problem
3. the macro BOOST_MPL_ASSERT_RELATION is reworked to avoid the problem

See http://gcc.gnu.org/bugzilla/show_bug.cgi?id=29518

The macro is:
    #define BOOST_MPL_ASSERT(pred) \
    enum { \
        BOOST_PP_CAT(mpl_assertion_in_line_,__LINE__) = sizeof( \
              boost::mpl::assertion_failed<false>( \
                  boost::mpl::assert_arg( (void (*) pred)0, 1 ) \
                ) \
            ) \
    }\
    /**/

It is apparently to do with the enum usage... I'm guessing
there is a good reason why this code (and others in the
boost/mpl/assert.hpp) uses enum directly rather than
BOOST_STATIC_CONSTANT?
