[csw-maintainers] GCC 4.7 release

[Maciej (Matchek) Bliziński]

I've got the new GCC built (some moons ago), but I can't release it,
because people complain they can't run it on older Solaris 10
releases. Yet they can't use the 4.6 version in dublin, they need the
4.7 version from unstable.

I want to find a way out.

There's a larger issue, what do we do with the kiel release. Do we
keep it compatible with pre-U10 (or pre-U9?) releases? If we do, how
do we do it? Yann spent a lot of time preparing maps, and I think
there are still problems. Some ways to proceed I can think of:

1. Set U10 (or U9?) as a requirement to run kiel, force users to bite
the bullet and upgrade.
2. Freeze kiel (but how do we release security fixes? Dago told me
it's hard to simultaneously have different Solaris 10 releases on the
buildfarm)
3. Fix whatever problems there are with function version maps.

We could also ask users what they think about it.

Your thoughts?
