Yes, there is (was?) a bug in ISL where they are missing extern "C" in
isl/val_gmp.h, which was hacked around in a buggy way in
graphite-isl-ast-to-gimple.c by including that file inside extern "C". I think
it should include system.h (or at least gmp.h) before doing that hack, to
minimize the number of headers recursively affected.

You could try building without ISL.

Could you possibly tell me how to do it and what the impact would be?

Thanks!

I think it should just work if you follow the instructions here:

I am wondering how should we handle this failure.  Create a new doloop test and
change this one testing the optimization gcc does now?

Thanks,

I tried to compile GCC 4.9.3 and I was unable, too. Different error but same
result. I recompiled GCC 4.9.2 and it worked.

I messed with different versions of "CLOOG" and "ISL" and I got GCC 4.9.3 and
5.1.0 working correctly.

I am currently using GCC 5.1.0 and compiling with it seems to work well. I
compiled Python, bind, etc., and it works.

I close this but report, but I would love future GCC releases to document what
CLOOG and ISL versions they require.

Thanks for your time.

It already does, see gcc/doc/install.texi in the source tarball.
