testcase

In the attached code, A::B is private to A. Yet, outside of A, I can still
create an alias template T which refers to A::B, and can instantiate that alias
template without errors generated. As I recall, this should fail upon
instantiation of the template.

Note that this does require an alias template. A regular alias or typedef
behaves correctly and generates an error.</pre>
