Above I was referring to a fortran front-end (like gfortran) being
available under a more permissive license (BSD/MIT. etc) If that was
true then it would be possible for a commercial compiler (PGI/Intel)
to take the front-end and then just make it emit the IR needed.

Certainly not an exhaustive list :)

1) Vet the codebase (stated this clearly)
2) Listen to what people say - (What needs to be worked on, are people
open to things like dual licensing, what's the future of Fortran,
For whatever reason someone at Apple has decided to work on "flang".
I'm not sure if the code is public or even a serious effort at all.
Apple certainly has the resources to toss at it, but outside of
someone's personal hobby project I can only think of one reason to
spend time on it.
1) Our goal (PathScale) is to implement F2K3/8
2) My personal goal is to advocate and push open source
# Possibly more important than either of the two points above
3) I'd like to see a larger Fortran community grow out of gfortran.
(This of course largely depends on if the contributors are more
interested in keeping it locked up to gcc or increasing Fortran
btw - I appreciate the feedback and information from everyone so far..
