[Bug c++/14777] New: typedef doesn't fully expose base class type

["mdorey at bluearc dot com" <gcc-bugzilla at gcc dot gnu dot org>]

template <typename T>
struct B
{
protected:
  typedef int M;
};

template <typename T>
struct A : B<T> {
  typedef typename B<T>::M N;
  A (int = N ());
};

A<int> a = A<int> ();

Produces:

Connection.cpp:5: error: `typedef int B<int>::M' is protected
Connection.cpp:14: error: within this context

With recent snapshots (eg gcc 3.4.0 20040324 - can send full version guff if it
wouldn't just be more clutter for you to read).  Sorry, that's as simple as I
managed to make the example - I did try everything I could think of to simplify
it further.

Interestingly, or perhaps not, this does compile when I think it shouldn't. 
It's the same thing except for char instead of int in the typedef for N.

template <typename T>
struct B
{
protected:
  typedef int M;
};

template <typename T>
struct A : B<T> {
  typedef typename B<char>::M N;
  A (int = N ());
};

A<int> a = A<int> ();
