Can it be done so that it I can still use cl-position in emacs 23.4.1?
Maybe by including in cl-lib-0.4 some byte-recompilation of the
cl-seq.el functions that Glenn mentions:

   (defun remove* (cl-item cl-seq &rest cl-keys)
   (defun delete* (cl-item cl-seq &rest cl-keys)
   (defun cl-delete-duplicates (cl-seq cl-keys cl-copy)
   (defun substitute (cl-new cl-old cl-seq &rest cl-keys)
   (defun position (cl-item cl-seq &rest cl-keys)
   (defun search (cl-seq1 cl-seq2 &rest cl-keys)

This was only for cl-position.
