Seconded.  I intend to leave CLooG-PPL with no more changes
other than bug fixes, in particular I will not update CLooG-PPL
to configure with PPL-0.11 to incite people to use CLooG.org.
My intent is to deprecate the use of CLooG-PPL, and remove
support of CLooG-PPL in GCC-4.7.

Ok.

Ok.

We will have to add to CLooG several defines to be able to determine
from configure the version of CLooG and the back-end that will be used
(Parma, ISL, PolyLib).

We need a configure maintainer to approve these changes.
Paolo, could you please have a look at the changes in [PATCH 3/3]?

Thanks,
