I have used an older binutils version: 2.9.1. You are right, that 2.13.1
doesn't complain BUT that doesn't mean thats better... GAS simply emits
zeros where the older gas complained. I would like to see compatibilty
with older versions.

The bug is still present in the second 3.3 prerelease: "3.3 20030509
(prerelease)". You should look at the generated code with "-O" and with
"-O -fgcse". GCC shouldn't emit references to (local) symbols that aren't
present in the first place. I call that broken.
