[Bug c++/31323] typename A::B * p; in template definition, with curiously recurring template inheritance

Or smaller like this:
------------------
template <class T> struct Base {
        typename T::X X;
};

struct A : Base<A>
{
    typedef int X;
};
------------------

sunCC also rejects it. I tend to believe that the code is invalid because
at the time where we instantiate Base<A> (in the base class list of A), A 
is not complete and so the inner typedef is not available yet.

What makes you think that the code should compile?
