From beaf3a26a60d5b0429a577b7d58232957d4483e7 Mon Sep 17 00:00:00 2001
From: Haru <haru@dotalux.com>

Subject: Added Makefile.in change detection (and auto-rebuild) capabilities

- If a Makefile.in is changed, ./config.status (or ./configure in case
  it's not available) will be automatically run to update the Makefiles.
- Special thanks to Yommy for the idea.
