[Bug c++/39269] New: Invalid template friend declaration accepted

["bangerth at gmail dot com" <gcc-bugzilla at gcc dot gnu dot org>]

This code has erroneously been accepted since at least gcc 2.95:
--------------------------
namespace NS {
  template <int A, int B> class X {};
}

class Y {
    template <int> friend class NS::X;
};
--------------------------
Note the wrong number of template arguments in the friend declaration.
The code is correctly rejected if X is not in a namespace.
