- *
- * $Log: mp-mem.c,v $
- * Revision 1.5  2001/06/16 12:57:00  mdw
- * Implement some missing functions.
- *
- * Revision 1.4  2001/02/03 12:00:29  mdw
- * Now @mp_drop@ checks its argument is non-NULL before attempting to free
- * it.  Note that the macro version @MP_DROP@ doesn't do this.
- *
- * Revision 1.3  2000/06/17 11:45:09  mdw
- * Major memory management overhaul.  Added arena support.  Use the secure
- * arena for secret integers.  Replace and improve the MP management macros
- * (e.g., replace MP_MODIFY by MP_DEST).
- *
- * Revision 1.2  1999/12/10 23:19:02  mdw
- * Improve error-checking.
- *
