0.pre7.24:
	got rid of :SB-PROPAGATE-FLOAT-TYPE and
		:SB-PROPAGATE-FUN-TYPE as separate target *FEATURES*
		options controlling the build, instead hardwiring
		them to always on; and rewrote
		CROSS-FLOAT-INFINITY-KLUDGE so that stuff like
			#!+sb-propagate-foo-type
		becomes
			#-sb-xc-host ; (See CROSS-FLOAT-INFINITY-KLUDGE.)
		instead; and similarly stuff like
			#!-sb-propagate-foo-type
		becomes
			#+sb-xc-host ; (See CROSS-FLOAT-INFINITY-KLUDGE.)
	--
	Remember to delete 'em from base-target-features.lisp-expr.
	Build SBCL with itself to test this change, since I had so
		much trouble with it.
	Document :SB-PROPAGATE-FOO-TYPE changes in NEWS.
