The previous version (0.23) seems to be not present in the
repositories anymore:

For the future, perhaps we could look into saving a copy of it
somewhere, and perhaps request GCC folks to not delete old versions?

Additionally, the isl.gforge.infria.fr is offline, so it could be
removed.  Nix has found some alternative URLs:
<https://github.com/NixOS/nixpkgs/commit/53a60ad361e020275b3f50c68a7f17411e5f8fd2>,
perhaps they could be added (if they still work)?

Is the source code of the other versions of isl in Guix still
available?

Given that isl is a dependency of GCC, does this cause a world-rebuild?
