>Description:
The code below generates the following error with a recent
snapshot:

$ gcc -c test.cpp
test.cpp:13: `struct A::B' does not declare a template type

It gives an ICE in 2.95.2.
>How-To-Repeat:
struct A
{
    struct B {
        B () { }
    };
};

template <class T>
struct C: A {
    friend A::B::B ();     // 2.95.2 ICE
    friend struct A::B;    // 2.97 error
};

template class C<char>;
