If the nested class is declared in an enclosing namespace scope (as required)
but still with the nested-name-qualifier of the derived type, G++ accepts it:
namespace N { struct A { struct Inner; }; }
namespace NN { struct AA : N::A {}; }
struct NN::AA::Inner {};
Clang++ and Comeau both reject this.
