OpenBSD uses clang 8 or gcc, depending on the architecture. From
brief testing, clang 8 doesn't implement __attribute__((fallthrough))
or /* FALLTHROUGH */.
That means to implement it in OpenBSD it'd require at least updating
the system compiler to clang 10 and possibly update gcc architectures
to clang before changing all of the FALLTHROUGHs. This is scope creep
well beyond what I'm willing to engage in :-)

No, because this test is used to with -Werror to determine which
warnings the compiler accepts. If I did that it'll cause gcc to flag
it as an error and have the effect of disabling the warnings on gcc
too.

Good judgement comes with experience. Unfortunately, the experience
usually comes from bad judgement.
