That should work.  Can you fill me in on what bug you're fixing?  Are
you trying to avoid a warning on code like:

  // No declaration of `strcmp'
  void f () { strcmp ("abc", "def"); }

I don't think we should do that, if that's what you're suggesting.

But, maybe you're doing something different?
