The main issue is that the test in configure is brain-dead and demands an explicit version.
Any reason not to fix that?
As far as I remember, the explicit version was set at that time to
ensure bug reports are reproducible and behavior does not change
depending on the isl version used. Different isl versions may change the
behavior as the results produced are not always canonical. Meaning
some conditions may e.g. be "if (a == 0 || a == 1)" in the old version
and "if (a == 1 || a == 0" in the newer version. We could solve this
issue by printing the isl version in the extended isl version output.
Opinions?
