--- Comment #6 from Manfred Schwarb <manfred99 at gmx dot ch> ---
There is ./configure --disable-isl-version-check,
but I doubt that it will help. The thing is, isl-0.13 needs
cloog-0.18.2 (or rather, cloog-0.18.1 needs isl-0.12.2 and does
not build with isl-0.13), which is not yet released.

Now I heard that the goal is to do without cloog, but I guess
the configure machinery (and probably, the rest of the graphite code)
is not yet up to it.

There really needs an immediate solution to this issue,
I think ATM there is no way to build graphite without resorting to
non-released libraries.

I suggest to revert all these isl-0.13 dependencies until cloog-0.18.2
is released, or there is shown some way to build graphite without cloog.

Roman, how is one supposed to build GCC with graphite support?
