0.6.11.42:
	MNA port (sbcl-devel 2001-04-14) of DTC cmucl-imp patch: Use
		VALUE-CELL objects rather than conses for the
		interpreter's value cells.
	more ANSI compliance: BREAK binds *DEBUGGER-HOOK* to NIL
		before calling INVOKE-DEBUGGER.
	SIGINT handling no longer uses CL:BREAK (which rebinds
		*DEBUGGER-HOOK* before doing INVOKE-DEBUGGER, screwing
		up --noprogrammer handling) but instead calls
		INVOKE-DEBUGGER more directly.
	NOPROGRAMMER-DEBUG-HOOK-FUN now terminates "normally"
		(calling Unix exit(3), not falling into infinite
		recursion in Lisp-level error trapping) even
		when shell/pipeline/SIGINT or other mischief hoses
		its low-level output streams.
	renamed FASLOAD and SLOLOAD to LOAD-AS-FASL and LOAD-AS-SOURCE,
		so that users have a better chance of understanding
		them when they appears in BACKTRACE
