0.8.16.9:
	Backend renaming of various BASE-CHAR things to CHARACTER things
	... BASE-CHAR-REG -> CHARACTER-REG
	... BASE-CHAR-STACK -> CHARACTER-STACK
	... BASE-CHAR-SC-NUMBER -> CHARACTER-SC-NUMBER
	... etc.
	... as a somewhat unexpected side effect, the BASE-CHAR class
		gets deleted, essentially because of the note containing
		"BOGGLE" in src/compiler/generic/primtype.lisp: array
		specializations are converted to primitive types by
		testing the specifier of the specialization against a list
		with EQUAL, and the BASE-CHAR/CHARACTER ambiguity hurts.
		Just as in June 2003, this looks too hard to solve right now.
