--- Comment #2 from Martin Sebor <msebor at gcc dot gnu.org> ---
Clang also diagnoses more interesting cases where the control variable is used
so if GCC implements a similar warning (which I agree would be useful) it
should handle those as well.  Such an implementation would most likely need to
be done later than in the front-end, so setting Component to middle-end.

void f (int);

int main()
{
  for (int i = 0; i < 2; )
  {
    f (i);
  }
}
