0.6.9.13:
	(The "version broken" problem above was because the change
		in POLICY type was not binary compatible, and I didn't
		bump the version number, and I was crashing in some
		private .sbclrc code compiled under the old system.
		Oops..)
	The POLICY-QUALITY type no longer includes NULL.
	renamed more PCL stuff for unintern after warm init
