Will tree-ssa be GCC 3.5?

Thank you for a reasonable and useful reply.

And this is where the concern lies in funding tree-ssa development. If
my goal is to have a professional-quality "free" Fortran 95 compiler,
should I put my money and time into GCC, another project (Open64), or
develop from scratch?

Given the uncertainties of tree-ssa's future, anyone with a specific
need is likely to allocate resources toward more definite, if less
ideal, projects.

The new GNU Fortran 95 compiler (gfortran) is deliberately tied to 
tree-ssa; unless I'm mistaken, Fortran 95 support will only exist in 
mainline GCC if tree-ssa becomes mainline.
