At Red Hat, we had about six months once the choices became apparent,
and you can see what choice we made.  I personally have no time (in
fact, probably negative time) to do it in; I'll be lucky to get a
working glibc with the not-publicly-available toolchain I'm using now.

I believe that if we had been able to predict the strength of the
reaction to using a GCC snapshot in our main Linux distribution, we'd
have consulted more in advance about the possible choices but
ultimately we would have still done it, because there were no other
good choices. The position for Debian is a bit different, because you
don't sell compiler support; one of the big factors influencing our
choice was that we didn't want to be supporting a four-year-old
compiler in 2002.

Well, I'll let you guys worry about it.  Tell me if you do want a branch.
