;;; Commentary:
;;
;; Flymake is a minor Emacs mode performing on-the-fly syntax checks.
;;
;; This file contains a significant part of the original flymake's
;; implementation, a buffer-checking mechanism that parses the output
;; of an external syntax check tool with regular expressions.
;;
;; That work has been adapted into a flymake "backend" function,
;; `flymake-proc-legacy-flymake' suitable for adding to the
;; `flymake-diagnostic-functions' variable.
;;
;;; Bugs/todo:

;; - Only uses "Makefile", not "makefile" or "GNUmakefile"
;;   (from http://bugs.debian.org/337339).
