What's wrong with:

template < typename T >
struct is_wchart_specialized
{
    BOOST_STATIC_CONSTANT( bool, value = true );
};

template <  >
struct is_wchart_specialized<unsigned char>
{
    BOOST_STATIC_CONSTANT( bool, value = false );
};

//...

template <  >
struct is_wchart_specialized<unsigned long>
{
    BOOST_STATIC_CONSTANT( bool, value = false );
};

Then checking "is_wchart_specialized<wchar_t>::value"?  (Of course, this
only works at regular compiler time, not preprocessor time.)
