MSVC-7.1 outputs the same result. During previous experiments I even 
checked that is_const<remove_reference<Value> >::value was true inside 
const_ref_global_fun_base (static asserted) and even that

typename remove_const<
         typename remove_reference<Value>::type>::type

was a different type than

typename remove_reference<Value>::type

But for some reason MSVC fails to see both overloads as different.

Best,
