  28 ;; Flymake is a minor Emacs mode performing on-the-fly syntax
  29 ;; checks using the external syntax check tool (for C/C++ this
  30 ;; is usually the compiler)

  32 ;;; Bugs/todo:
  33
  34 ;; - Only uses "Makefile", not "makefile" or "GNUmakefile"
  35 ;;   (from http://bugs.debian.org/337339).
