Not at this time.  But we could probably remove a number of false
positives.  For one, we currently print a warning even for:

template <class T>
class foo {
  friend int bar(int);
};

because uses_the scope of foo<T>::bar(int) refers to T.  Here's a patch
that fixes this.  Ok to install, if it doesn't introduce any
regressions?  Mainline and branch?
