Fixed for GCC 6 by r227023, which fixed PR 66957.

The examples here look different enough that we should probably add them to the
testsuite before closing this.

// Clang compiles without errors.
class B {
protected:
  void f() {}
};

template 
struct S;

template 
struct S{
template 
static void caller(T *p) {p->B::f();}   // error: 'void B::f()' is
protected
//static void caller(T *p) {p->f();}// Ok
};

class Q : B{
template  friend struct S;
};

int main(){
Q q;
S::caller(&q);
return 0;
}

Reduced:

template
struct A;

template
struct A
{
  template
  void f(U* u) {
u->T::g();
  }
};

struct B {
protected:
  void g() { }
};

struct C : B {
  template friend struct A;
};

int main()
{
  C c;
  A a;
  a.f(&c);
}

The partial specialization does not match the friend declaration for some
reason, I think it should do.
