You can put a conditional around the lot, but I don't remember that
sort of situation actually occurring in code I've worked on.

As I said, it's easy to suppress undefined function warnings safely if
you compile file-by-file in batch, for instance with dummy autoloads
for them inside eval-when-compile.  There's probably a case for
something like `(defun fred)' being treated by the optimizer like
`(defvar fred)', but I'm surprised this is such a big deal.
