3.4.x is very stable for me, and produces much faster code for c++
apps than 2.x branch.

I probably shouldn't ask that quesiton, but did anyone contact gcc ppl
I am lurking gcc stuff acctively, and I remember ongoing discussin on
their list about 2.x branch, when 3.4 was released. I know also that
there is planty of bugs fixed for 2.x branch, but no new release was
made for looong time. Maybe we should persuade them to release 2.97 or
