--- Comment #8 from Manfred Schwarb <manfred99 at gmx dot ch> ---
The graphite-isl-ast-to-gimple.c code reads
#ifdef HAVE_cloog
#include <isl/set.h>
#include <isl/map.h>
#include <isl/union_map.h>
#include <isl/ast_build.h>
#if defined(__cplusplus)
extern "C" {
#endif
#include <isl/val_gmp.h>
#if defined(__cplusplus)
}
#endif
#endif
and val_gmp.h only exists in isl-0.13.
So maybe things work when disabling/not using cloog?
Will have to check tomorrow.
