Yes, it should also warn for non-constants, and also for other floating
decreases in accuracy such as: 

float foo(double x) {
  return x;
}

I should have time to create a patch for this before 4.8 goes into stage 3.  Do
you think it needs a copyright assignment and if so what paperwork would you
need from my employer?
