Well actually there's no need to put the ifdefs around such an extern
declaration at all. The one small downside to omitting the ifdefs is
that a programming mistake may then be revealed at link-time instead of
at compile-time. But we very often omit the ifdefs, because reducing visual
clutter is more important.
