0.8alpha.0.13:
	CLISP build megapatch
	... mostly putting #-SB-XC in front of :COMPILE-TOPLEVEL,
		because clisp gives a full warning for function and
		macro redefinition;
	... workaround clisp's buggy pretty printer by not exercising it
		as much: use (INHIBIT-WARNINGS 3);
	... explicit :INITIAL-ELEMENT 0 when we're using 0 to mean
		"uninitialized" in MAKE-ARRAY;
	... SPECIAL-OPERATOR-P isn't a good test on the host for what
		can become a target macro;
	... slightly more portable floating point logic:
		Explicitly set *READ-DEFAULT-FLOAT-FORMAT* so that we
			don't create host LONG-FLOATs by accident;
		LOAD-TIME-VALUE magic for negative floating point zeros;
	Minor associated text file frobbage
	... braindump some unrelated TODO items
	Obligatory runtime code improvement
	... fix one warning in gencgc.h
