+	Clean up KKCC code related to DEBUG_XEMACS.  Rename
+	kkcc_backtrace() to kkcc_backtrace_1() and add two params: a
+	`size' arg to control how many stack elements to print and a
+	`detailed' arg to control whether Lisp objects are printed using
+	`debug_print()'.  Create front-ends to kkcc_backtrace_1() --
+	kkcc_detailed_backtrace(), kkcc_short_backtrace(),
+	kkcc_detailed_backtrace_full(), kkcc_short_backtrace_full(), as
+	well as shortened versions kbt(), kbts(), kbtf(), kbtsf() -- to
+	call it with various parameter values.  Add an `is_lisp' field to
+	the stack and backtrace structures and use it to keep track of
+	whether an object pushed onto the stack is a Lisp object or a
+	non-Lisp structure; in kkcc_backtrace_1(), don't try to print a
+	non-Lisp structure as a Lisp object.

+	* specifier.c:
+	New macros IF_OLD_GC(), IF_NEW_GC() to simplify declaration of
+	Lisp objects when a finalizer may exist in one but not the other.
+	Use them appropriately.
+
+	* extents.c (finalize_extent_info):
+	Don't zero out data->soe and data->extents before trying to free,
+	else we get memory leaks.
+	
+	* lrecord.h (enum lrecord_type):
+	Make the first lrecord type have value 1 not 0 so that 0 remains
+	without implementation and attempts to interpret zeroed memory
+	as a Lisp object will be more obvious.

+	* syntax.c (uninit_buffer_syntax_cache):
+	* text.h (eifree):
+	If possible, whenever we call xfree() on a field in a structure,
+	set the field to 0 afterwards.  A lot of code is written so that
+	it checks the value being freed to see if it is non-zero before
+	freeing it -- doing this and setting the value to 0 afterwards
+	ensures (a) we won't try to free twice if the cleanup code is
+	called twice; (b) if the object itself stays around, KKCC won't
+	crash when attempting to mark the freed field.
+
+	* rangetab.c:
+	Add a finalization method when not NEW_GC to avoid memory leaks.
+	(#### We still get memory leaks when NEW_GC; need to convert gap
+	array to Lisp object).
