All you need to do to make the above work on MSVC (or any other compiler
that does not support partial class template specialization) is to write

    #include "boost/type_traits/broken_compiler_spec.hpp"
    BOOST_TT_BROKEN_COMPILER_SPEC(HWND)

somewhere in a header that gets included everywhere where the type traits
constructs are used on HWNDs.
