;;; This function switches C-mode so that it indents stuff according to
;;; our style(9) which is equivalent to FreeBSD's. Tested with emacs-22.3.
;;;
;;; Use "M-x bsd" in a C mode buffer to activate it.
;;;
;;; To make this the default, use a line like this, but you can't easily
;;; switch back to default GNU style, since the old state isn't saved.
;;;
;;; (add-hook 'c-mode-common-hook 'bsd)
;;;
;;; As long as you don't have this in the c-mode hook you can edit GNU
;;; and BSD style C sources within one emacs session with no problem.
