IMHO, there's no good reason for someone to spend the time to try to make gcc10-bootstrap build on Sonoma, even if with sufficient efforts such a thing might be possible.

It's a port used for bootstrapping newer gccs on older systems, and bootstrapping clang-11-bootstrap.

It should just be marked as unbuildable on whatever newer systems it doesn't currently build on, and move on to spend your time on something more fruitful

This is fixed by Kirill today. Now it works beautifully on Sonoma.

Bypass all mad zoo of clangs, for example :)

pointless, but good to hear I guess

You are right, I was thinking by habit about older Intel systems, where building clangs is insane, and numerous versions are required – so switching to gcc altogether would make life easier. On Sonoma there is no zoo of clangs, of course :) (Yet, if someone wanted to avoid clang on Sonoma, going via gcc10-bootstrap would still be sensible.)
