0.8.1.15:
	Mostly MIPS goodies, though some infrastructural fixes too
	... fix hideous DEFINE-PARTIAL-REFFER constant-case bug;
	... also adjust the costs so that the constant reffers and
		setters are prioritized;
	... also build fix for undefined static symbols (reported by
		KMR end June 2003)
	... include src/runtime/Config in tools-for-build/Makefile
		(and adjust order of events in make-config.sh to
		ensure that src/runtime/Config exists by the time
		we need to build any of the tools-for-build)
