I happened to notice today that, while the rest of the buildfarm is free
of implicit-fallthrough warnings, jacana is emitting a whole boatload of
them. It looks like it must have a different idea of which spellings of
the "fall through" comment are allowed. Could you check its documentation
to see what it claims to allow?

regards, tom lane
