Subject: [PATCH 12/12] configure: Compile with -Wimplicit-fallthrough=2
Date: Fri, 11 Dec 2020 16:24:26 +0100 [thread overview]
Message-ID: <20201211152426.350966-13-thuth@redhat.com> (raw)
In-Reply-To: <20201211152426.350966-1-thuth@redhat.com>
Coverity always complains about switch-case statements that fall through
the next one when there is no comment in between - which could indicate
a forgotten "break" statement. Instead of handling these issues after
they have been committed, it would be better to avoid them in the build
process already. Thus let's enable the -Wimplicit-fallthrough warning now.
