Description
Summary:

Steps to Reproduce:

Compile the following program:

(defmacro generate (&body body)
  (let ((table (make-hash-table))
        (forms '()))
    (dolist (item body)
      (destructuring-bind (def name &rest args) item
        (declare (ignore def args))
        (print item)
        (setf (gethash name table) item)))
    (maphash (lambda (k v)
               (print v)
               (push v forms)) table)
    `(progn ,@forms)))

(generate
 (defvar *a* 1)
 (defvar *b* 2))

(defun f ()
  (+ *a* *b*))

(eval-when (:compile-toplevel)
  (pprint (macroexpand '(generate
                         (defvar *a* 1)
                         (defvar *b* 2)))))

Expected Results:

It is expected that no warning about variables *A* and *B* be issued.
It is expected that the macroexpansion printed would be:

 (progn 
   (defvar *a* 1)
   (defvar *b* 2))


Actual Results:

We get warnings about undefined special variables.
We get the following expansion:

 (progn)
