Consider the following fragment:

{
  double sin ();
  double (*fun) ();

  fun = sin;
  printf ("%f %f", fun(1), (*fun)(1));
}

Both invocations of fun work and give the correct result. But it seems that one
of the invocations is wrong (the first). Why do they both work? Will they always
work in all cases?
