You could do this, but better might be this:

(defun my-c-initialization-hook ()
  (define-key c-mode-base-map "\C-m" 'c-context-line-break))
(add-hook 'c-initialization-hook 'my-c-initialization-hook)

, as suggested by the (current) CC Mode manual (page "Sample .emacs
File").  

This gives you proper continuation of comments and macros as well as
indentation of ordinary statements.  Note also that you don't need to use
c-mode-common-hook here - it wouldn't do any harm, but you only need to
bind the key once, not every time you open a fresh CC Mode buffer.
