Quick question: why do you want to do this?  comment-dwim has M-; as a
standard key binding, which is surely just as easy to type, and just as
(un)intuitive ;-).

However, if you just want to do this for no particular reason, .....

C Mode itself binds C-d to c-electric-delete-forward.  More to the point,
it binds it in the keymap c-mode-base-map, and this keymap takes
precedence over the global keymap.  So, if you want your global key
binding to be seen, you'll have to suppress the local keybinding.
Something like this (untested) should work:

(define-key c-mode-base-map "\C-d" nil)

That is, if you _really_ want to do it.
