I think we want to suppress the warning on instantiation even if the order is
reversed:  given

int foo;

template <typename T>
struct bar
{
  void qux () { baz (); }
private:
  void baz () { int foo; }
};

int main ()
{
  bar <int> ().qux ();
}

We first warn about the declaration in the template, and then again about the
instantiation.
