Yes, it looks like it is. I added -fno-strict-aliasing and the perl
benchmarks passed when compiled with ToT GCC. That makes me feel better
about the idea of putting Peter's patch (with the revert) on the 4.3
branch as a way to fix the HPPA bad code generation bug. I am going to
test that patch on the branch and verify that it fixes my SPEC/GCC
failure.
