[Bug c++/15639] New: Fails to find inherited function

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

template<typename T>
class A{
public:
    T*  F(int i) { return 0;}
    };

template<typename U, template<typename> class B>
class C: public B<U> {
public:
    void    G() {
        U* u = F(5);
        }
    };
int main() {
    C<bool, A> c;
    c.G();
    return 0;
    }

gives:

~/ootbc/common/test/src$ g++ foo.cc
foo.cc: In member function `void C<U, B>::G()':
foo.cc:11: error: there are no arguments to `F' that depend on a template parameter, so a declaration of `F' must be available
foo.cc:11: error: (if you use `-fpermissive', G++ will accept your code, but allowing the use of an undeclared name is deprecated)


However, the explicit invocation of C<bool, A> binds U to bool and B to A, so the "c" derives from A<bool>, which does in fact have an F(int) to call and is available.
