Well, the Solaris Studio compiler produces "warning: statement not
reached" messages, as seen for example on buildfarm member castoroides.
I don't have one available to experiment with, so I'm not sure whether
it knows that abort() doesn't return; but I think it rather foolish to
assume that such a combination doesn't exist in the wild.
