Subject: GNU Superopt patches 2/6
This one moves Aux Stuff into a seperate file:

Tues Aug 31 2010  Joseph Seymour  <Seymour@IceraSemi.com>

	* aux.c: New file containing 'Aux Stuff' previously after main in
	superopt.c.
	* superopt.c: Removed 'Aux stuff'.
	* superopt.h: Added check to superopt.h so only parsed by cpp
	once.
	* Makefile: Added aux.c
