--- Comment #3 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Your testcase doesn't compile anywhere, you need to add at least a semicolon
after case 0:
With that fixed, whether this was accepted or not changed over time several
times, e.g. 3.2 accepted it with warnings (and -fpermissive in all cases), 3.3
- 4.9 emitted a warning and error, 5.x-8.x gave just a warning or two, 9.x
error + warning.
I'd say just fix the legacy code.
