It also supports "-Wswitch-default", which seems to be the exact opposite of
clang's "-Wcovered-switch-default". Personally I think gcc's "-Wswitch-default"
is the better one to listen to; having a default case is a good back-up even if
it will never actually be reached. Here is a link to a post that explains it
better than I could: http://programmers.stackexchange.com/a/242896/161051
