--- Comment #5 from David Edelsohn <dje at gcc dot gnu.org> ---
One needs to upgrade to ISL 0.14 or 0.15.

The earlier inclusion ordering of ISL header files in graphite source files
were wrong and did not follow GCC requirements.  It worked on Mint and OpenSUSE
because GCC header file requirements were violated.
