	* AU_StackNode.hh (new): set half word to SORT_UNKNOWN rather than
	relying on allocateMemoryCell()
	(new): call initFlags()
	(new): clean up; update comments; initFlags() becomes
	clearAllFlags()

2004-06-08  Steven Eker  <eker@goo.csl.sri.com>

	* AU_StackSort.cc (revComputeBaseSort): fixed nasty bug where we
	were failing to take account of a sort calculated for part of a
	list and therefore ignored that part of the list for sort
	calculation purposes
	(fwdComputeBaseSort): fixed symmetric bug
