3.3.4 status, and some questions

[Joe Buck <Joe dot Buck at synopsys dot COM>]

I took a look at bugzilla and a first snapshot of what the release notes
would be like, if we released now, appear below.

I have some questions:

- I successfully built 3.3.3 on an ia64 GNU/Linux box and did not observe
  a bootstrap failure.  Was 13918 something that only a very few people
  observed, or was it common?

- Is 14302 the bug that caused XFree86 4.3 builds to fail on Debian ARM?

- Are there other bugs that the Debian folks have patched in their
  gcc-3.3 that we don't have in the FSF 3_3_branch?  (That's why I'm
  copying you, Matthias).

Ideally I'd like to see Debian sarge be able to come out with a compiler
that is as close to 3.3.4 as possible.  I'd also like us to tighten up
now on what we allow into 3.3.4, as we need to focus on rock-solid
stability.  Every patch has a non-zero probability of introducing some
new bug, so beyond fixing something that blocks the building of a
distribution, we should be close to done now.
