0.pre7.86.flaky7.4:
	(This version dies with an AVER failure in FIND-IN-PHYSENV
		again, this time in xc of typep.lisp. Maybe, since
		I'm now substantially more knowledgeable about
		PHYSENVs than I was a few weeks ago, this will be
		easier to debug.)
	fixed bug which caused target-sxhash problem. PAIRLIS: "The
		new pairs may appear in the resulting association list
		in either forward or backward order." Egads. This is
		why the xc dies in target-sxhash: It's not a problem
		in &OPTIONAL handling, it's that I used (PAIRLIS ...)
		in a recent rewrite of LABELS as though it were
		(MAPCAR #'CONS ...), and the code breaks because
		PAIRLIS reverses the order on me. So..
	..Rewrite DEF-IR1-TRANSLATOR LABELS more thoroughly, so it
		loses its dependence on the order of PLACEHOLDER-FENV.
