To put this in a (timeline) perspective:

On the 18th of March, 2000, I announced Andy Vaught's work on the g95 
front-end to the gcc-patches mailing list.

In 2004 (!) we merged the resulting compiler and run-time library into 
the gcc (cvs) repository (obviously, after the tree-ssa infrastructure 
went in - 2004-05-17, but before the creation of the 4.0 release branch 
- 2005-02-25). Then it took another 2 months for 4.0 to be released.

Unless PGI manages to summon massively large (parallel) working groups 
to accomplish this, it might take a few years to fruition.
