Hello,

during update of quite an old setup I found that gcc-4.9.3 fails to build with isl-0.11.1 which is still in the tree.

It build fine with isl-0.15 on the same box, so please update version requirements (probably in the toolchain.eclass).

I'm not really sure what version requirement should be minimal, but since both gcc-4.9.3 and isl-0.12.2 are stable, you should test that version.

gcc-4.9 doesn't need this header
