commit 88d99fc1bd87b17517e49fd7ae82c0de6eaff992 Author: Nick Mathewson nickm@torproject.org Date: Tue Sep 22 09:59:37 2020 -0400
Fix warnings when using two unusual options together.
The option `--enable-all-bugs-are-fatal` when used with `--disable-module-relay` caused GCC to warn about functions that it thought should be labeled noreturn.
I've tried a couple of approaches, but disabling the warning on these functions seems to be the best approach.
