It seems to me that it would be better still to put

    #ifdef BOOST_NO_INTRINSIC_WCHAR_T
        BOOST_STATIC_ASSERT(is_same<unsigned short, wchar_t>::value);
    #else
        BOOST_STATIC_ASSERT(!is_same<unsigned short, wchar_t>::value);
    #endif

after the conditional definition of BOOST_NO_INTRINSIC_WCHAR_T to
verify that the macro has been set/unset correctly.
