;;; Commentary:
;;; Register `cc-mode' for `smart-jump'.
;;; This file is pretty hacky since cc-mode doesn't provide the language feature.
;;; Adding `smart-jump-register's here that are related to `cc-mode'.
;;; I would love if someone had an idea on how to fix this elegantly.

;;; Code:
(require 'smart-jump)

(defvar rtags-rc-binary-name)
