Subject: class friend declaration doesn't allow use in class scope

Not a bug. The clause you referred to:
"A name nominated by a friend declaration shall be accessible in the scope of
the class containing the friend declaration."
actually means that the following code is not allowed:
class A { class B {}; };
class C {
friend class A::B; // Error - A::B is not accessible inside C
};
For your case, look at 11.4 paragraph 9:
"For a friend class declaration, if there is no prior declaration, the class
that is specified
belongs to the innermost enclosing non-class scope, but if it is subsequently
referenced,
its name is not found by name lookup until a matching declaration is provided
in the innermost
enclosing nonclass scope."
