kees added a comment.

I should clarify: I still need the =3 mode. Since sizeof([0]) == 0 and sizeof([]) == error, they are being treated differently already by the compiler causing bugs in Linux. The kernel must still have a way to reject the _use_ of a [0] array. We cannot reject _declaration_ of them due to userspace API.
