It DOESN'T for me with: 2.95.2, 3.2, 3.2.1, 3.3. 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. > This should be reclassified as change request. I can confirm that > the compiler doesn't do an optimization that looks valid to me. Raimar -- email: rf13@inf.tu-dresden.de The trick is to keep breathing.
