-O2 failure went away this weekend, hurray

>Nice!

Yes, I'm excited too! This is great news. I don't know what is up with
the last failure, the thread test. I'm not too worried about it at the
moment, either.

Okay. Also, since the autocrasher has those mystery fails for some of
the wchar_t tests, I'd appreciate it if you could give more info. I'm
not quite sure what is up with that, or the libgcc_so issue.
