0.pre8.98:
	Fix for MEMBER type (as per cmucl-imp 2003-04-23)
	... (MEMBER 0.0) is not the same as (SINGLE-FLOAT 0.0 0.0);
	... (MEMBER 0.0 -0.0) is the same as (SINGLE-FLOAT 0.0 0.0)
	... (NOT (MEMBER 0.0)) needs to be
		(OR (NOT SINGLE-FLOAT)
		    (SINGLE-FLOAT * (0.0))
		    (MEMBER -0.0)
		    (SINGLE-FLOAT (0.0)));
	... add some tests for this one.
	In the process of this fix, make -0.0 and -0.0d0 dumpable by the
	cross-compiler:
	... more special cases in src/code/cross-float.lisp.
	And also let an :SB-SHOW build proceed to the end
	... don't try to print the slots of PCL objects.
