--- Comment #14 from Brooks Davis <brooks@FreeBSD.org> ---
Reverting on a temporary basis sounds like it may be the right short-term
solution, but it's clearly not a sustainable option. Delaying until (for
example) LLVM 16 would let upstreams and some linux distros do some of the work
for us, but I don't really know how much that will help.

If we do to the reverting-to-warning route, it would be good to provide a
fairly reliable path for people to re-enable the errors (I'll have an llvm15
port later this week) and to notify maintainers of broken port so we can spread
out the work.

Throwing out another idea: would be be possible to more or less automatically
test which ports are fixed by USE_CSTD=gnu89? IMO, splatting those in pretty
indiscriminately would be fine for ports of software written to 23+ year old
standards.
