Double ugh. Since gcc 3.0.4 was just released.
Are there any other know binutils/gcc synchronization problems? I think
gcc 3.0.4 was intended to be the end of the gcc 3.0.x releases but
binutils and gcc 3.0.4 have enough synchronization problems, it might
be worth discussing a 3.0.5 just so the two GNU projects co-exist
nicely.
