(defvar foo)

works to silence the compiler since at least Emacs 21.4 (I think).

declare-function works since Emacs 23.1, and exists as a no-op in Emacs
22.2 and 22.3.

I hope that one day cc-bytecomp can just be removed. The part that deals
with "an older CC Mode with outdated macros [being] loaded during
compilation" is clever, but IMO just adds a bunch of complexity to solve
a problem that doesn't need solving. Files should be compiled in batch
mode in a separate Emacs instance.
