GCC 3.3

[Mark Mitchell <mark at codesourcery dot com>]

We have about 50 open high-priority PRs representing regressions
against GCC 3.3.

I've heard a few people say that "all the open PRs are C++ PRs" -- but
that's clearly false, looking at the list below.  It's true that we
C++ folks have our work cut out for us, but there are plenty of back
end and optimizer issues in the list below.

At this point, I'm going to change the rules for the 3.3 branch
slightly.  In particular, compile-time improvement patches need to get
normal approval from a maintainer *and* a review by me.  I'm going to
be leery of anything that doesn't look obviously simple and correct to
me.  We've made a lot of good improvements in this regard, and there
are a few more patches I think we can get in, but it's time to focus
on the out-and-out crashes and bad code generation problems.

Please look through this list and see if you can't knock a few of
these out.

I think we are getting pretty close; some of these PRs are duplicates,
and some can get downgraded if we can't fix 'em readily.

Gaby, you would make my life a little simpler if you'd take some of
the high-priority bugs that are only 3.2 regressions and close them,
after applying patches to the 3.2 branch if you want to do that.
There are now a lot of 3.2-only PRs open, and it's hard to see what's
a 3.3 PR and what's a 3.2 PR in GNATS.  This is GNATS' fault...

Thanks,
