I've fiddled with this a bit, and the following works well

---

(global-set-key "\C-w" 'clipboard-kill-region)
(global-set-key "\M-w" 'clipboard-kill-ring-save)
(global-set-key "\C-y" 'clipboard-yank)

(unless window-system
  (defun copy-region-to-xsel()
    ;;(with-current-buffer (current-buffer)
    (call-process-region (region-beginning) (region-end) "xsel" nil 0
nil "-p" "-i"))
  ;; )
  (defun ext-kill-ring-save()
    (interactive)
    (copy-region-to-xsel)
    (kill-ring-save (region-beginning) (region-end)))
  (defun ext-kill-region()
    (interactive)
    (copy-region-to-xsel)
    (kill-region (region-beginning) (region-end)))
  (global-set-key "\M-w" 'ext-kill-ring-save)
  (global-set-key "\C-w" 'ext-kill-region))

---

although I would prefer to have the three first lines within an
"if-then-clause" and the rest within an else clause, but I have not
figured out how to do this, I get "Invalid function: (global-set-key
^W (quote clipboard-kill-region))"

(if window-system
(
  (global-set-key "\C-w" 'clipboard-kill-region)
  (global-set-key "\M-w" 'clipboard-kill-ring-save)
  (global-set-key "\C-y" 'clipboard-yank)
)
  (
  ...
   )
)


Sorry to be responding to myself, I just thought the above might be
valuable for future reference. Thank for all the help!
