Synopsis: Erroneous access controls in friend function parameter initializer

State-Changed-From-To: open->closed
State-Changed-By: bangerth
State-Changed-When: Thu Jan 16 14:29:14 2003
State-Changed-Why:
    This is already fixed in mainline, which will eventually
    become gcc3.4. I guess one of Krian's patches achieved this.

>Description:
The following code is copied from the C++ standard (section 11, clause 5)

class A {
	typedef int I;
	I f();
	friend I g(I);
	static I x;
};

A::I A::f() { return 0; }
A::I g(A::I p = A::x);
A::I g(A::I p) { return 0; }
A::I A::x = 0;

It generates an erroneous access error for A::X as shown below:
