Surely there is a variable that indicates whether winring has been
initialized yet.  Assuming that variable is called winring-initialized:

(defun ecb-window-configuration ()
   (if (derived-mode-p 'c-mode)
       (progn
	(ecb-activate)
	(unless winring-initialized
	  (ecb-winman-winring-enable-support)
	  (winring-initialize)))
     (ecb-deactivate)))

(add-hook 'window-configuration-change-hook 'ecb-window-configuration)

Have you considered asking the experts at ecb-list@lists.sourceforge.net
(see http://lists.sourceforge.net/lists/listinfo/ecb-list)?
