Topic: Qualified name lookup

Hi!
I would like to know your opinions about the following case of
qualified name lookup. Let consider the example listed below.
I looked in the standard specification but I am not sure of what
is the right way a compiler has to proceed.
Let us consider the qualified identifier N::A::B in the member function
h.
Which B is meant according to the standard C++ in the function h with
N::A::B b;
is it ::N::A::B or ::C::N::A::B ?
The name lookup is in two steps: first name lookup for the nested name
specifier N::A
of the qualified identifier N::A::B and then unqualified name lookup of
B in the scope N::A.
The question is now how to proceed for the first step.
Thanks for any hint.

class C{
public :
class N{
public :
class A {
public:
class B {
public: void f(){ cout<<"::C::N::A::B::f()"<<endl; }
};
};
};
};
class N{
public:
class A : public C{
public:
class B {
public :
void f(){ cout<<"::N::A::B::f()"<<endl; }
};
void h(){
N::A::B b;
b.f();
}
};
};
