Ok, but a very long time ago there was a recommendation to do not use cl
package when writing code in Emacs Lisp.

Is that recommendation no more valid?

Well, so:

A) (cond ((eq ps-print-emacs-type 'xemacs) ...)
        (t ...))

B) (cond ((featurep 'xemacs) ...)
        (t ...))

Are you saying that A and B above are treated differently by the
byte-compiler??
