The method you gave may not work. Who says that "unsigned short" is
the type that "wchar_t" rips off? What about something like:
// If wchar_t is a distinct type, this version will be used
template < typename T >
BOOST_STATIC_CONSTANT( bool, value = false );
// Do this specialization for every built-in integral type
// EXCEPT wchar_t
template < >

BOOST_STATIC_CONSTANT( bool, value = true );
