That's why I originally was going to have /xx be fatal for 5.26. But the fact that it was fatal during essentially the entirety of the 5.25 series without a single BBC report convinced me it was ok to go ahead and change the meaning.

It seems that right now we're breaking autoconf by making this fatal.
*Autoconf*. It has been fixed in their repository, but they haven't
done a stable release in years. Think of that what you want, but
there's a staggering amount of software depending on autoconf.
I don't see how we can not revert this fatalization given these
circumstances. The advantages are too theoretical to offset this very
practical problem, and reverting would give us at least a year to deal
with autotools' release inertia.
