[Bug c++/15453] New: Friend declaration not treated as a declaration in scope.

["igodard at pacbell dot net" <gcc-bugzilla at gcc dot gnu dot org>]

In the following example:

template<typename G, template<typename H> class I = B>
class J;

template<typename C, template<typename D> class E>
class F {
    template<typename G, template<typename H> class I = B>
    friend
    class J;
    template<typename K, template<typename L> class M = B>
    friend
    class N;
    friend
    class O;

    J<int, B>* j;
    N<int, B>* n;
    O* o;
    };

int main() {
    return 0;
    }

N appears to not be recognized as a template (in the declaration of n) based on its declaration as a template friend, whereas exactly the same declaration with an additional declaration in file scope is acceptable (template class J, declaring j), as is a friend declaration of a plain class. The c++ rules in this area are incomprehensible to me, but admitting friend declarations in one case and not the other seems unreasonable if not incorrect.
