Expected behavior of CL special forms, 'labels' and 'flet', inside macros.

[Jon Strait]

Hello,

I thought I'd run this issue by the list in case someone who's worked on 
the CL extension code can say that it's the proper behavior and not 
worth submitting a bug report on.

Basically, I tried using a 'labels' form to bind a function inside a 
macro to be used recursively and it wasn't working. (Lisp nesting 
exceeds max error)  Then, I switched the 'labels' with 'flet', which 
ended up working fine, but not until after having to change the binding 
name as well.  Using the same name for 'flet' as was previous used for 
'labels' resulted in this strange error:

"Use `labels', not `flet', to rebind macro names"

Is seems for some reason, the 'labels' functions binding name was 
registered with a macro name as well.

Be advised, this is only in the context of testing both the macro and 
the calling code with eval-last-sexp inside a buffer.

For the sample macro I created below, the first argument is a list of 
items and every subsequent argument is a lambda function taking one 
argument, to apply in sequence to the initial argument list using mapcar:

(defmacro map-chain (init-list &rest mfuncs)
 (setq mfuncs (reverse mfuncs))
 (flet ((fmap (init-list mfuncs)
           (if (null mfuncs)
           init-list
             `(mapcar ,(car mfuncs) ,(fmap init-list (cdr mfuncs))))))
   (fmap init-list mfuncs)))

(map-chain '(7 8 9) (lambda (x) (* x 10)) (lambda (y) (+ y 4)))


I'm currently using Emacs 23.0.92

Thanks,
Jon
