Preprocessed file exhibiting the problem

The templated member contructor is unable to access the private
class members of its const ref argument.  Since that argument
is an instance of the same class, my understanding is that it should
be able to.

------- Comment #4 from pinskia at gcc dot gnu dot org  2006-09-22 16:27 -------
No, template classes can only access their own types in that A<int> can only
access the private variables of A<int> and not A<float>.
If you want A<int> to access A<float>'s private variables add to the class:
template<class T2> friend class A;

Which says that A<T> is a friend to A<T2>.
