------- Comment #1 from pinskia at gcc dot gnu dot org 2007-07-15 21:05 -------
What is happening is that for the switch statement, we don't know that the
value can't be just 0 or 1 at the point where we warn. We should be able to
lower this switch statement into an if statement and get better results.
