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.)
