The following code:

template<typename T>
struct A {
  typedef A type;
};
                                                                               
                            
template<typename T>
struct B : A<T> {
  using typename A<T>::type;
  type f(type);
};

Give a "syntax error before typename." Without typename in the using
declaration, however, type in B<T> is not a typename, so f's declaration is not
well formed.

Because the "typename" is necessary, this is not the same as bug 3033.
