After only. I know the results of the GCC testsuite on SPARC/Solaris by
heart, there was not a single regression.

Yes, definitely. You were a bit perverse when you asked me to do this

As I have said since the very beginning, a version prior to 3.3.3 that

how buried in reorg.c the bug appears to be, that's next to impossible.
Anyway, you don't need to convince me, only the branch maintainer.
