At the end of gl/bindings.lisp there's an alternative implementation
of DEFGLEXTFUN that doesn't call compile or redefine anything. Does
that work better for you?

I tried this version:

(defmacro defglextfun ((cname lname) return-type &body args)
  (alexandria:with-unique-names (pointer)
    `(let ((,pointer (null-pointer)))
       (defun ,lname ,(mapcar #'car args)
         (when (null-pointer-p ,pointer)
           (setf ,pointer (gl-get-proc-address ,cname))
           (assert (not (null-pointer-p ,pointer)) ()
                   "Couldn't load symbol ~A~%" ,cname)
           (format t "Loaded function pointer for ~A: ~A~%" ,cname ,pointer)
           (push (lambda () (setf ,pointer (null-pointer)))
                 *gl-extension-resetter-list*))
         (foreign-funcall-pointer
          ,pointer
          (:library opengl)
          ,@(loop for arg in args collect (second arg) collect (first arg))
          ,return-type)))))

However, compilation of gl/funcs.lisp fails due to heap exhaustion
(using SBCL 1.0.55).
