It's not being used anymore. We got rid of it in favor of better APIs. Well, it's still being used in one place: a contrib/ patch, but I explicitly want to break it, so that someone reviews it. I don't want to modify it, since it's not being tested, so it would be very risky for me to touch it. Instead, let it bitrot, and if someone cares, they'll update it correctly. BTW, the comment that said /* danger -side effects */ was wrong: sizeof() doesn't evaluate the argument (unless it's a VLA), so there wasn't really a double-evaluation issue.
