Add the following lines to your .emacs:

(require 'hideif)

(defun hide-ifdef-region-internal (start end)
  (remove-overlays start end 'face 'font-lock-warning-face)
  (let ((o (make-overlay start end)))
    (overlay-put o 'face 'font-lock-warning-face)))

(defun hif-show-ifdef-region (start end)
  "Everything between START and END is made visible."
  (remove-overlays start end 'face 'font-lock-warning-face))

Save and (evaluate .emacs or) restart Emacs, open the file of
your choice, and do

M-x hide-ifdefs
