Ok.  I understand no warning needs to be posted, especially in light of
the eminent gcc-2.95 release that fixes the bug.  I think a silent codegen
bug for something as simple as pre and post increment *is* pretty big.
But, I didn't mean to sound as if I was that *bothered* by it.

I think egcs, now gcc, is a very good compiler and I applaud all the
volunteer effort that is put in.  I hope, though, that there is a test
case in the testsuite for something as basic as this.  It seems like an
embarrasing bug to let out the door.  I hope it was not known at release
time, or if it was, I hope it was going to be a bear to fix.

Thank you for the reply.
