0.6.11.5:
	MNA hack to DEFCONSTANT-EQX to support cmucl-2.4.19 as xc host
	patches ported by MNA from CMU CL..
	..no need to export the unused symbols %FUNCTION-HEADER-TYPE,
		%FUNCTION-HEADER-ARGLIST, and %FUNCTION-HEADER-NAME
	..Upon a stack trace ambiguity in X86-CALL-CONTEXT, choose the
		Lisp frame in preference to the C frame as this is the
		frame of interest.
	..Limit the stack trace failure warning in X86-CALL-CONTEXT to
		fails for the immediate frame rather then failures
		deeper within the search.
	..Catch missing slots in CONDITION-READER-FUNCTION, and signal
		an error.
	..PPRINT-NEWLINE, PPRINT-INDENT, and PPRINT-TAB should do
		nothing when *PRINT-PRETTY* is false.
	..Correct the pretty printing by PRINT-UNREADABLE-OBJECT. Only
		attempt to print pretty when the stream is a
		PRETTY-STREAM (and when *PRINT-PRETTY*) to ensure that
		all output goes to the same stream.
	..Have PRINT-UNREADABLE-OBJECT respect *PRINT-PRETTY*.
	..Fix OUTPUT-CHARACTER to escape the CHAR-NAME. Rework
		QUOTE-STRING to not write the delimiting quotes so
		that it can be used by OUTPUT-CHARACTER.
	..Within GENERATE-BYTE-CODE-FOR-SET, avoid trying to set a
		lexical variable with no refs since the compiler
		deletes such variables.
	..Within SET-LEAF-VALUE-LAMBDA-VAR, avoid trying to set a
		lexical variable with no refs since the compiler
		deletes such variables.
	..Rework the ASH DERIVE-TYPE optimizer to better handle large
		negative bounds. Based on suggestions from Raymond Toy.
	..Add a defensive declaration to PARSE-SPECIALIZERS.
	..Add a defensive declaration to PARSE-DEFMETHOD, as well.
	..Silence compiler warnings about undefined function
		<hairy-make-instance-name> when compiling a method
		containing a MAKE-INSTANCE call.
	..Correct the printing of instance objects for which the
		length was being incorrectly calculated.
