----------------
I think you'll need a member fn to have something to check the linkage of?  Might be worth checking instantiating a partial specialization gets things right too?  along the lines of ..

export template<typename> class C {};
template<typename T> class C<T *> { void M(){}; };

void Use (C<int *> &p) { p.M(); }
