I found it too be entirely too much work to be trusted and considered
stable long term. So therefore I generally kick ppl/cloog to the curb
and focus on core c,c++ gfortan and ada with objc thrown in without
the ppl/cloog bits at all. I have been very happy with my results and
the recent 4.6.3 RC was the most clean and pure results I have seen
to date, on Solaris 8 old Sparc no less :

Would be cool to say "entirely optional".
