From dc6514954049bf3d7c993996025a81414423c89b Mon Sep 17 00:00:00 2001
From: mrg <mrg@NetBSD.org>
Date: Sun, 3 Feb 2019 03:19:25 +0000
Subject: - add or adjust /* FALLTHROUGH */ where appropriate - add
 __unreachable() after functions that can return but won't in   this case, and
 thus can't be marked __dead easily
