0.pre8.24:
	Quieten the cross-compiler a little
	... SB!XC:PROCLAIM the forthcoming existence of a bunch of
		internal defining functions;
	... move PROPER-LIST-OF-LENGTH-P earlier, both for quietness
		reasons and for use within early-extensions;
	... delete some outdated commentary;
	... declare *TYPE-SYSTEM-INITIALIZED* special in target-type,
		since that's its first use.
	Bye bye BUG 6 (and a little more tidying up of BUGS)
