Обсуждение: jacana vs -Wimplicit-fallthrough

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

There doesn't seem to be any docco with it. What's odd is that fairywren
is supposedly using the identical compiler, but it's on msys2 while
jacana is msys1. I can't see why that should make a difference, though.
