So with that patch it works. Probably it worked even before your last fix, as I
think I cloned the first your repo just with the link above, but was on master,
not on the master-wip-config-darwin20, my fault. I compiled/bootstrapped now
with Apple clang version 12.0.0 (clang-1200.0.32.27), and just did make -i
install, skipping over the error, which I think is not relevant for me. I used
my patches for the gmp, mpfr, mpc, though I think it's not relevant for them.
In any case I notified their developers about the issue. Hope we get a stable
and convincing solution into 11.0.1. Will you then backport this for upcoming
10.3 and 9.4 as well? (for 8 it's probably too late).
