Please don't compare symbols with string= (which is meant for strings):

   (cond ((eq system-type 'windows-nt) (message "Microsoft Windows"))
         ((eq system-type 'darwin)     (message "Darwin"))
         ((eq system-type 'gnu/linux)  (message "Gnu/Linux"))
         (t                            (message "Unknown system")))
