This seems to work!
(defun my-c-mode-common-hook ()
  ;; my customizations for all of c-mode and related modes
  (setq c-basic-offset 3)
  (setq-default indent-tabs-mode nil) ; Use spaces, not tabs, for
indentation.
  (delete-selection-mode 1) ; Maybe on by default on windows and off by
default on solaris?
  )
(add-hook 'c-mode-common-hook 'my-c-mode-common-hook)

(defun my-cpp-mode-hook ()
  (c-set-style "ellemtel")
  (c-set-offset 'access-label '--)
  (c-set-offset 'topmost-intro '-)
  (c-set-offset 'inline-open '-)
)
(add-hook 'c++-mode-hook 'my-cpp-mode-hook)
