>Description:
	While we strive to save a few bytes here and there to fit in
	small install media, we waste a lot of space by including
	assertions and filename strings in install media
>How-To-Repeat:
	Run strings on "instbin"

>Fix:
	- perhaps compile a version without DIAGASSERT of the relevant
	  libc files?
	- figure out how to strip the pathnames of the source files
