commit 923f9ce5257203206ad6ed12b05f7d1576eb1ab0
from: Omar Polo <op@omarpolo.com>
date: Mon Jun 21 12:45:12 2021 UTC

work around some GCC warnings

clang doesn't emit any.  To be honest, some of them are actually right
(like the missing `void'), others are impossible but still it's not a
bad idea to initialize some variable.  Future me maybe will be
thankful.
