isl is not part of GCC, and I don't see this error in the version of
isl that gcc-10.3.0/contrib/download_prerequisites uses.
Using isl is optional anyway, you can just leave it out if you want.
Either way, this seems to be a problem with the version of isl that
MacPorts uses, not a GCC problem.

This line number doesn't match what's shown below, as it's coming from
line 13560 below (which is line 13496 in my copy of the gcc-10.30
sources, so maybe MacPorts patched it?)

This is harmless, but I see the problem and will fix it.

I'll see if I can find this one too. Also harmless though.
