As Stephan said, you're setting the global binding rather than the local
one.

A better function for doing what you want is `c-context-line-break' (I
think this was new with CC Mode 5.30).  This function also does the Right
Thing inside comments.

The best way of setting this is:

(define-key c-mode-base-map "\C-m" 'c-context-line-break)

at the top level of your .emacs.  [or, if you're not sure whether or not
CC Mode is going to have been loaded, this:

(eval-after-load "cc-mode"
  '(define-key c-mode-base-map "\C-m" 'c-context-line-break))

.]

If you haven't already got CC Mode 5.30, the place to get it is
<http://www.sourceforge.org/release.php>.

Have fun!
