Re: c++/9122: qualified name forced to be used in non-public derived class

Dear Neil

Sorry to bother you. But I still believe c++/9122 is a bug as the "p" in 
class "C" is not an access to the base of "C", but a newly defined pointer. 
Please see below:

class A {};
class B : A {
A* pp; // not full qualified, OK!
};
class C : public B {
public:
 C(A*);// compiler : `class A' is inaccessible
 void f(A*) {} compiler : `class A' is inaccessible
 A* p; // compiler : `class A' is inaccessible
 ::A* p2; // full qualified, OK!
};

I compiled the code with gcc2.95.3, VC7, BC5.5.1, all passed. And I looked 
up the C++ standard but have not found anything that forbid the sample code 
to compile.

Another point is if "A" in the sample was replace by "::A", all passed, it 
seems strange.

Best regards,
