 This looks inccorect according to 11.1 [#3] + DR #175.
 
 <--- part of DR 175 --->
 Proposed resolution (04/01):
 
 Add to the end of 11.1  class.access.spec paragraph 3:
 
 [Note: In a derived class, the lookup of a base class name will find the 
 injected-class-name instead of the name of the base class in the scope in 
 which it was declared. The injected-class-name might be less accessible 
 than the name of the base class in the scope in which it was declared.] 
 [Example:
 
 class A { };
     class B : private A { };
     class C : public B {
         A* p;    // error: injected-class-name A is inaccessible
         ::A* q;  // OK
     };
 
 --end example]
 
 What do you think Gaby?
