--- Comment #4 from Sebastian Pop <spop at gcc dot gnu.org> --- The release managers will decide the requirements and when lib versions will be deprecated. I am still investigating a fix to continue supporting ISL-0.14: we will add code to configure.ac to detect ISL version number based on which we will disable functionality that we know is broken for older ISL versions.
