The following example compiles cleanly with g++, while I think the "friend"
declaration should be rejected, as the templated private class "A::Inner"
should not be visible except from within A.
#include <iostream>
class A {
public:
static int h();
private:
template<typename T>
struct Inner {
static int f();
};
};
class B {
friend class A::Inner<int>; // Should not be visible
static int g() { return 42; }
};
template<>
int A::Inner<int>::f()
{
return B::g();
}
int A::h()
{
return Inner<int>::f();
}
int main()
{
std::cout << A::h() << std::endl;
}

11.4: A name nominated by a friend declaration shall be accessible in the scope
of the class containing the friend declaration.
Confirmed.
