;;
;; Flymake is a minor Emacs mode performing on-the-fly syntax
;; checks using the external syntax check tool (for C/C++ this
;; is usually the compiler)
;;; Bugs/todo:
;; - Only uses "Makefile", not "makefile" or "GNUmakefile"
;; (from http://bugs.debian.org/337339).

"If nil, flymake will run on copies in `temporary-file-directory' rather

If the file makes use of relative include paths it's quite possible that
setting this to nil will cause compilation errors. On the other hand, leaving
it set to t will trigger any automated file creation detection that is
watching your project directory. YMMV.
When editing a remote file via Tramp, this flag also has the side-effect of
determining whether the syntax check is run in the same place as the original
file (and thus on the remote machine), or in the same place as
`temporary-file-directory' (usually the local machine)."
