Like with the following.  Tested with both in-tree and out-of-tree 
ISL/CLooG.

Ok?

Thanks,

Richard,
   The committed change solves the build issues here. Any chance we can get the
newer tarballs from...

ftp://ftp.linux.student.kuleuven.be/pub/people/skimo/isl/isl-0.11.1.tar.bz2

and

http://www.bastoul.net/cloog/pages/download/cloog-0.18.0.tar.gz

added to gcc/infrastructure subdirectory on the gcc/gnu ftp sites?
          Jack

Done.

It seems we never remove files from that place ... I'll update
the recommended versions stated in install.texi and would eventually
