Oh I see what's going on, thank you for the explanation. Then I think all
that's needed here is a comment saying something along the lines of: Clang
implicitly returns 0 in C89 mode, but that's an extension, so we need to
perform the check in that case to ensure we emit the expected extension warning
in C89 mode.
