Just curious since `macroexp-parse-body' also takes care about it: Where
is `cl-declare' in this picture?  Is it relevant at all?

I'm asking since

------------------------- snip -------------------------
(byte-compile
 '(defun foo ()
    (cl-declare)
    (interactive)))
------------------------- snip -------------------------

gives the same "misplaced interactive spec" warning, but for a different
reason: The `cl-declare' gets replaced by nil somewhere before `m-p-b'
gets called, so `m-p-b' sees and returns:

-------------------- *trace-output* --------------------
1 -> (macroexp-parse-body (nil (interactive)))
1 <- macroexp-parse-body: (nil nil (interactive))
-------------------- *trace-output* --------------------

Thanks, will give it a try.
