template <int N> class B {
  protected:
    struct Inner {
        static int f();
    };
};

template <int N> class D : public B<N> {
  void f() { B<N>::Inner::f(); };
};
-----------------------------used to compile, but now yields
  tmp/g> /home/bangerth/bin/gcc-3.4-pre/bin/c++ -o /dev/null -c bug3.cc
  bug3.cc: In member function `void D<N>::f()':
  bug3.cc:3: error: `struct B<N>::Inner' is protected
  bug3.cc:9: error: within this context

I think this is wrong, since name lookup of B<N>::Inner
should happen from within the inheritance hierarchy, not
go outside.

The bug is kind of fragile: if I remove any template args,
or make Inner::f a static variable instead of a function,
then everything compiles fine. This is strange...
