   1. 编辑你的.emacs配置文件
      vi ~/.emacs 或 emacs ~/.emacs
   2. 将以下函数粘贴到你的.emacs文件内

;;Highlight #if 0 to #endif     (defun my-c-mode-font-lock-if0 (limit)       (save-restriction         (widen)         (save-excursion           (goto-char (point-min))           (let ((depth 0) str start start-depth)             (while (re-search-forward "^\\s-*#\\s-*\\(if\\|else\\|endif\\)" limit 'move)               (setq str (match-string 1))               (if (string= str "if")                   (progn                     (setq depth (1+ depth))                     (when (and (null start) (looking-at "\\s-+0"))                       (setq start (match-end 0)                             start-depth depth)))                 (when (and start (= depth start-depth))                   (c-put-font-lock-face start (match-beginning 0) 'font-lock-comment-face)                   (setq start nil))                 (when (string= str "endif")                   (setq depth (1- depth)))))             (when (and start (> depth 0))               (c-put-font-lock-face start (point) 'font-lock-comment-face)))))       nil)     (defun my-c-mode-common-hook ()       (font-lock-add-keywords        nil        '((my-c-mode-font-lock-if0 (0 font-lock-comment-face prepend))) 'add-to-end))     (add-hook 'c-mode-common-hook 'my-c-mode-common-hook)     ;;Highlight end

3. 重新启动Emacs看看^_^
