From 5129b24c4e34e43c69d1c229cf2f91ccfffee1ba Mon Sep 17 00:00:00 2001
From: Joel Sherrill <joel.sherrill@OARcorp.com>
Date: Wed, 20 Jun 2007 22:19:38 +0000
Subject: 2007-06-20	Ray Xu <rayx@gmail.com>

	* optman/Makefile.am, optman/preinstall.am: Add stubs for file system,
	console, and libio. This shrinks the memory requirements but Joel has
	not figured out how best to present this to application space.
	* optman/no-console.c, optman/no-filesystem.c, optman/no-libio.c:
	New files.
