It looks like adding -Wno-c23-extensions would only work with more
recent clang versions, so it wouldn't actually fix the build problems,
just make them even harder for developers to actually notice.

Oh well. It's not like this is all that common a problem, so I think
we'll just have to live with it, and hope that people don't do that
"label at end of statement" very often.

(I think it's case statements too, not just labels, too lazy to look
up the details again)
