21.3 [FATAL CORE LISP BUG] dolist broken in subr.el

User-agent: Gnus/5.1003 (Gnus v5.10.3) Emacs/20.7 (windows-nt) (i386-*-nt5.0.2195)

I just found out why all my lisp files were broken under 21.3.  

Why there are double definitions of cl*el function and macros in the
subr.el is beyond my understanding. Whoever made the decision that the
cl*el implementation must be "rewritten" or "doubled" in subr.el
should be shot at dawn.

Remove cl's  subr.el rewrites and do it right:

    (t)Dump a Emacs whose core includes the whole of cl*el and
    deliver that version of Emacs in the future.

In my opinion that is the only right path; same as what XEmacs team
has taken.

Try this in 21.3 with subr.el loaded and you know what I mean:

  (dolist (elt '(1))

Debugger entered--Lisp error: (no-catch --cl-block-nil-- nil)
  cl-block-throw(--cl-block-nil-- nil)
  (return-from nil nil)
  (progn (return) (setq --dolist-temp-- (cdr --dolist-temp--)))
  (while --dolist-temp-- (setq elt (car --dolist-temp--)) (progn (return) (setq 
--dolist-temp-- ...)))
  (let ((--dolist-temp-- ...) elt) (while --dolist-temp-- (setq elt ...) (progn 
... ...)) nil)
  (dolist (elt (quote ...)) (return))
  eval((dolist (elt (quote ...)) (return)))
  (setq ad-return-value (ad-Orig-eval-last-sexp eval-last-sexp-arg-internal))
  (let (ad-return-value) (setq ad-return-value (ad-Orig-eval-last-sexp 
eval-last-sexp-arg-internal)) (save-excursion (ignore-errors ...) (let ... 
...)) ad-return-value)
* call-interactively(eval-last-sexp)
