If you mean with "worked" that it had omitted the test in the past: I
don't know. It is a new issue for me which I think gcc should
optimize.

I have also tested intel compiler 6.0 and 7.0 and both don't do the
optimization. The sun compiler (Sun WorkShop 6 update 2 C 5.3) however
will do the optimization if -depend is given.
