The one I described earlier:

C:\emacs\trunk> bin\emacs.exe -batch -Q -f batch-byte-compile lisp\doc-view.el

In toplevel form:
doc-view.el:614:1:Warning: Unused lexical variable `item'
Wrote c:/emacs/trunk/lisp/doc-view.elc

where line 614 points to this function:

(defun doc-view-remove-if (predicate list)
  "Return LIST with all items removed that satisfy PREDICATE."
  (let (new-list)
    (dolist (item list (nreverse new-list))
      (when (not (funcall predicate item))
        (setq new-list (cons item new-list))))))
