G++ 4.6.0 and later correctly compile this
namespace A { template < class PIX > class B; }
void f(A::B<int>&);
template < class PIX > class A::B {
friend void ::f(A::B<int>&);
PIX z;
};
void f(A::B<int>& i) { int a = i.z; }
int main() {
A::B<int> b;
f(b); // 1. error: f is ambiguous (no, there is no 2nd declaration!)
::f(b); // 2. error: z is private (yes, but 'f' is a friend)
// A::f(b); // 3. error: f is not a member of A (of course)
}
So I think this bug is fixed
