Bug ID: 61490
Summary: accepts-invalid: qualified-name in friend function
definition
Product: gcc
Version: 4.9.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org

testcase.cpp
namespace N { void f (); }
struct A {
friend void N::f () { } // violates [class.friend]p6
};
int main () { }
-----------------------------------------
`gcc` inaccurately accepts the above snippet, even though we are
referring to a qualified-name in our friend definition, something
which is ill-formed according to [class.friend]p6:
> A function can be defined in a friend declaration of a class if and
> only if the class is a non-local class (9.8), the function name is
> unqualified, and the function has namespace scope.
