	hello,

	i was trying to find the bug xf86 - but sad that i also deleted my
	core files , log files etc.  when deleting the compile tree and
	didnot have the time to compile it again . btw, the problems seems
	in programs/xserver/mi/miregion.c (as i remember) with the sorting
	code. just compile with -O2 or another compiler , and it runs
	without problems.
