Description of changes

Clang 16 defaults to C++17, which does not allow the register storage class specifier. This is fixed upstream and will be included in 1.23.0, but the commit with the fixes does not apply cleanly, so a patch is provided instead of using fetchpatch.

I'm keeping my eye on this. However, it's looking like the 1.23 release of Groff might not be far off and I'm hopeful we can avoid carrying the big patch ourselves.

I consider waiting for the next release feasible until such time as this becomes a true blocker.

According to the latest status update, it looks a release is imminent (possibly this week). I’ll keep this PR open until it the new version is released in case #241692 is merged before that happens, and we need to fix the groff build in the meantime.

Great work on this @reckenrode!! (Un)fortunately(?) groff 1.23.0 has been released making the changes proposed in this PR no longer necessary.
