0.8.20.17:
	suppressed a VERIFY-BACKTRACE test, because it seems to be
		broken independent of the haiblefixes I'm merging
	merged various fixes from Bruno Haible sbcl-devel 2005-03-10.
		(Note that some can't be properly exercised w/out a
		Mac or CLISP, but since they were self-evidently broken
		before (e.g., #+DARWIN or SUBTYPEP where only #!+DARWIN
                or SB!XC:SUBTYPEP makes sense), I merged them on the
		theory that it can't be making things fundamentally
		worse.:-)
	(+ unrelated .cvsignore tweaks to reduce general CVS nagging)
