the fenv bug is not new and was reported via #100017, there is already a
discussion with two possible solutions. The title is a bit misleading, I hi=
t it
when I bootstrap a rootfs with all libs and headers for the armv7 target.=20

it seems that the fix for my gcc-10 bug was a stray commit without any bug
report, so I don't know who and where to ask for a proper backport. Gentoo's
gcc maintainer trofi (Sergey Trofimov) has resigned, to my great misfortune=
, so
I'm kind of lost with the process. Can we at least reopen? The bug is def n=
ot
fixed in the gcc-10 branch.=
