Mainline in regression-fix mode after Thanksgiving

[Mark Mitchell <mark at codesourcery dot com>]

I've been staring at Bguzilla for about a week now trying to figure
out what to make of the fact that there are more than 200 regressions
open against GCC 3.4.  True, some of these are low-priority (MMIX or
Ada bugs for example) -- but most are not.  There are 110 wrong-code,
rejects-valid, or ice-on-valid regressions.  That's negative progress
from October 26th.

I realize that people are agressively using the compiler, and that
bugs reported is partially a function of the amount of use.  I also
understand that with all the changes we've got in this release, there
are bound to be some problems.  However, I think that we've got to
take steps to get things in hand.

Therefore, effective 12:01 AM Friday, November 26th PST, the usual
release-branch rules will be in effect on the mainline.  So,
regression-fixes only.  Patches submitted before that date can still
be applied, but other patches will need to be queued for either (a)
the mainline (if I lift the release-branch rules before we branch) or
(b) GCC 4.1 (if I do not).  Port/language maintainers please respect
this constraint.

The Objective-C++ situation is a special case; the SC has made it a
priority to get that functionality into 4.0.  Therefore, I'm going to
give Zem and Geoff until December 3rd to figure out what to do, and
convince anyone else who needs to be convinced.  Otherwise, I'm going
to postpone Objective-C++ until 4.1.
