+ *	Avoid include redundancy
+ *	Include only if finding memory leaks.

+ *
+ *  Include File:	LYLeaks.h
+ *  Purpose:		Header to convert requests for allocation to Lynx
+ *			custom functions to track memory leaks.
+ *  Remarks/Portability/Dependencies/Restrictions:
+ *	For the stdlib.h allocation functions to be overridden by the
+ *		Lynx memory tracking functions all modules allocating,
+ *		freeing, or resizing memory must have LY_FIND_LEAKS
+ *		defined before including this file.
+ *	This header file should be included in every source file which
+ *		does any memory manipulation through use of the
+ *		stdlib.h memory functions.
+ *	For proper reporting of memory leaks, the function LYLeaks
+ *		should be registered for execution by atexit as the
+ *		very first executable statement in main.
+ *	This code is slow and should not be used except in debugging
+ *		circumstances (don't define LY_FIND_LEAKS).
+ *	If you are using LY_FIND_LEAKS and don't want the LYLeak*
+ *		memory functions to be used in a certain file,
+ *		define NO_MEMORY_TRACKING before including this file.
+ *	The only safe way to call the LYLeak* functions is to use
+ *		the below macros because they depend on the static
+ *		string created by __FILE__ to not be dynamic in
+ *		nature (don't free it and assume will exist at all
+ *		times during execution).
+ *	If you are using LY_FIND_LEAKS and LY_FIND_LEAKS_EXTENDED and
+ *		want only normal memory tracking (not extended for
+ *		HTSprintf/HTSprintf0) to be used in a certain file,
+ *		define NO_EXTENDED_MEMORY_TRACKING and don't define
+ *		NO_MEMORY_TRACKING before including this file.
+ *  Revision History:
+ *	05-26-94	created for Lynx 2-3-1, Garrett Arch Blythe
+ *	10-30-97	modified to handle StrAllocCopy() and
+ *			StrAllocCat(). - KW & FM
+ *	1999-10-17	modified to handle HTSprintf0 and HTSprintf(),
+ *			and to provide mark_malloced, if
+ *			LY_FIND_LEAKS_EXTENDED is defined. - kw
+ *	2003-01-22	add sequence-id for counting mallocs/frees -TD
+ *	2004-04-27	ANSIfy'd -TD
+ *	2012-02-09	add bstring interfaces -TD
