0.7.1.17:
	merged the second of the two patches (the one that's not
		supposed to work) from Dave McDonald's "patch for CLISP
		compilation" message (sbcl-devel 2002-02-03)...
	...made reader macro functions BACKQUOTE-MACRO and COMMA-MACRO
		return single values, as described by ANSI and enforced
		by CLISP
	...used SLOT-VALUE instead of DEFSTRUCT-generated slot
		setters. (ANSI allows structure slot setters to be
		implemented either as SETF functions or as SETF
		expanders. Some SBCL code in vm-macs.lisp assumes
		they're functions, and forward references them, which
		doesn't work in CLISP, which uses SETF expanders.)
	...coerced float-tran.lisp float literals to DOUBLE-FLOAT
		(since CLISP was defaulting them to LONG-FLOAT and then
		getting confused)
	...added :ADJUSTABLE T for some MAKE-ARRAYs (where the old
		code had unportably relied on :FILL-POINTER T causing
		adjustableness to happen)
	tweaking the patch...
	...went back to using DEFSTRUCT-generated slot setters
		(since (1) under ANSI, SLOT-VALUE's behavior for
		STRUCTURE-OBJECTs is explicitly unspecified by ANSI,
		and (2) in SBCL, SLOT-VALUE is defined in terms of
		PCL machinery, and so isn't available in cold init)
		and solved the forward reference problem by
		rearranging build order instead
