--- Comment #8 from Aldy Hernandez <aldyh at gcc dot gnu.org> 2013-02-05 23:52:30 UTC ---
Confirmed with cloog 0.18 and isl 0.11, both installed in /build/install, and
configuring GCC with:

/source/gcc/configure --disable-bootstrap --disable-multilib
--enable-languages=c,c++,fortran --with-cloog=/build/install
--with-isl=/build/install
