Package: emacs
Version: 24.3

Byte-compiling the following works fine in Emacs 24.2, but in 24.3
and later it fails with:

  foo.el:3:1:Error: Symbol's function definition is void: cl--arglist-args

;; foo.el:
(eval-when-compile (require 'cl))
(define-modify-macro foo (&optional (n 1)) +)


As warned by the compiler:

  emacs-lisp/cl.el:724:1:Warning: the function `cl--arglist-args' is not
    known to be defined.

Looks like I messed up this part when switching to gv.el.
But since noone noticed until now, I guess we should simply remove
define-modify-macro.

Oh, wait, no, it looks like the problem is just that cl--arglist-args
is not autoloaded from cl-macs.el.  So the compilation will succeed if
you use a CL macro before wetting to the define-modify-macro.

Should be fixed now,
