For those types (POD) you can always rely on specialization.

template<>
struct _UseSwap<int> {
     {enum{_M_type = 1 };};
};

What's the problem ??
But maybe there is something I do not understand.

Then I would say that it is a pity that POD are under-types in C++ (you 
cannot derive from them, can't ask for some properties, ...). I 
really believe that this should be changed, but that's another story.
