Re: [PATCH] Support official versions.

without including the documentation changes in the same commit.

That was not mentioned in the discussion of the patch. In fact I suppose Cloog-PPL was simply not tested. Andreas, did you try all possible configurations?

Also, if I understood correctly ISL and PPL are different ways to "do the same thing", and they should cause no differences in code generation. I assumed this because the patch didn't require any testsuite adjustment. Is this the case? If so, we only need to document the new possible choice of Cloog libraries.

If not, however, as Joseph said we need: 1) documentation of the new prerequisites; 2) a --enable-cloog-ppl option to enable Cloog-PPL tests _and_ disable Cloog-ISL at the same time. In this case, I suggest reverting the patch on trunk.
