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

+/*
+ * Copyright (c) 1994, University of Kansas, All Rights Reserved
+ *
+ * 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
