Yeah, these functions are definitely on their "SDL banned list". I don't
know how they implement that. At that level, I'd really expect it to be
done with a deprecated attribute next to the declaration (I also
considered trying to add deprecation attributes, too, but I think it's
hard to do without re-declaring the function, and anyway it's "just" a
warning).
