As has been pointed out already in this thread (by Laszlo, I think),
STATIC may trigger 'unused symbol' warnings that break the build under
our warnings-as-errors policy, since the compiler can infer that no
external references exist. So while STATIC is absolutely the way
forward, #define'ing it in a way that affects existing code is likely
to cause problems.
