Hi,

I'd like to ask some rules regarding the scope of a friend declaration
which are not discussed (as far as I could tell) in the ARM.  
Given the ff. code:

  class B { protected : enum A {}; };
  class C : public B {
    friend class A;   // According to the scoping rules, A refers to B::A.
                      // Since B::A is not a class, should we flag an error
                      // or do we declare a new class A since there is no
                      // existing type symbol in the scope of class C?
  };

Thanks for any replies.
