Seconded.

Merging tree-ssa into mainline, renaming the whole thing as the next
GCC-4.x.y series and allowing time for other front-ends to adjust 
and GCC developers to adjust to the new framework is, I believe, an
action we should seriously consider.  
In the meanwhile, we can continue work on the gcc-3_4-branch to
produce the GCC-3.4.x and (GCC-3.5.x if needed). 
If we don't do something like that, I'm afraid people will
"abandon" mainline and focuse on tree-ssa (which would become a de
factor mainline), therefore causing more confusions than would a proper
merge. 

The impression I've gotten from the thread that led to the sudden
gcc-3.4.x branching was that some major vendors are going to skip
GCC-3.4.x entirely, and they don't see any benefits in delaying
branching.  I suspect most of those vendors are going to concentrate
efforts on tree-ssa (if not merged to mainline).  I suspect that would
lead to another pshychodrama.
