0.6.12.14:
	fixes from Arthur Lemmens' 2001-05-05 sbcl-devel message I..
	..wrapped an EVAL-WHEN around the definition of +EMPTY-HT-SLOT+
	..removed irrelevant COUNT term in in LOOP form in
		compiler/x86/call.lisp
	..moved DEFCONDITION SIMPLE-TYPE-ERROR from error.lisp to
		late-target-error.lisp
	..moved DEFUN DO-PENDING-INTERRUPT from signal.lisp to
		target-signal.lisp, since its definition ("magically
		converted to a BREAK instruction") only makes sense
		to Python (and causes a warning in Lispworks)
