And I would not want to see that happen either, nor do I think Florian
would, or many of the other participants in this thread.

Indeed, for some projects, where it's hopeless^Wlots of work,
we're using -std=c89 or -std=gnu89 as appropriate - as already stated.

But most things are easy to fix.

Our interest is purely in making the default stricter for better UX,
reducing the net amount of these bugs in the wild, and avoiding
regressions when we fix these problems. Trying to remove C89 entirely
would, if nothing else, be needlessly antagonistic, but some of the
replies seem to act as if we have.
