28;;; Commentary:
29;;
30;; Flymake is a minor Emacs mode performing on-the-fly syntax
31;; checks using the external syntax check tool (for C/C++ this
32;; is usually the compiler)
33
9f812d23
SM		 34;;; Bugs/todo:
35
36;; - Only uses "Makefile", not "makefile" or "GNUmakefile"
37;; (from http://bugs.debian.org/337339).
