[Ecls-list] Two more problems

I downloaded the CVS-tree and rebuilt ECLS. No regexp.lisp
compiles without problems.

Unfortunately I ran into two more problems.

I tried the following example code that I found in "ecldev.html".
This compiles but at load-time I get a segmentation fault.

(Clines "

       int tak(x, y, z)
       int x, y, z;
       {      if (y >= x) return(z);
               else return(tak(tak(x-1, y, z),
                               tak(y-1, z, x),
                               tak(z-1, x, y)));

;;;  TAK calls the C function tak defined above.
(defentry tak (int int int) (int tak))

Segmentation violation.
Wrong type argument to a compiled function.
Broken at LOAD.


The 2. problem is:

(defun get-package-symbols (package &key (describe nil))
  (let ((pack (find-package package)))
	(if (eql nil pack)
		(format "No package ~A~%" package) 
	    (loop for s being each external-symbol of (find-package 
package) do
		  (if describe
			  (progn (describe s) (terpri) (princ "--------------
			  (print s))))))

> (get-package-symbols 'si)
The function #:G119 is undefined.

Did I do anything wrong? I would be very appreciative for help.
