[223e237]1Submitted By: William Harrington <kb0iic at cross-lfs dot org>
2Date: 12-28-2015
3Initial Package Version: 5.2.0
4Origin: Idea originally developed by Ryan Oliver and Greg Schafer for
5 the Pure LFS project with help from
6 Martin Ward
7Upstream Status: Not Applied - CLFS Specific
8Description: This patch makes changes to the paths for pure64, eg 64bit libs
9 in /usr/lib, 32bit in /usr/lib32.
10Comment: Renamed for GCC 5.3.0
