Ubuntu did plan the 2008 April release (8.04) with a compiler taken
from the 4.2 branch; the main repository is already fixed to build
with 4.3 and build tests are run regularily, so a change to 4.3 could
be considered. About 5% of the packages needed a change to build with
4.3 (most of them added C++ headers).

Debian's next release will be around fall 2008 (or later, when its
ready), considering 4.3 as the system compiler, hopefully for all 10+
architectures.

Both distributions do not rebuild the archive by default when changing
the compiler version, so the new compiler is only used for new package
uploads.

For previous releases APIs of runtime libraries were changed up to
close the release date. This makes it somewhat difficult to already
use a prerelease version of the compiler in the distribution (or all
packages uploaded between the compiler upload and the upload of a
fixed comiler need to be rebuilt, which might be difficult for the
slower Debian architectures). Would the GCC developers consider an
ABI/API freeze somehwat between beginning of stage3 and the release?
