Yes, I meant gcc (version 2.96 20000731).  I've verified that the bug still
exists in gcc3.0, but I haven't been able to create a testcase yet.

By "cc" do you mean gcc?  If so, what version?  Can you check whether
the bug still occurs with the latest version of gcc (gcc3.0 or, better
still, gcc3.1-prelease) or provide a test-case?
