-/*----- Revision history --------------------------------------------------*
- *
- * $Log: mp-mem.c,v $
- * Revision 1.6 2004/04/03 03:30:22 mdw
- * Fix long-standing stupidity in @mp_dest@.
- *
- * 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.
- *
- * Revision 1.1 1999/11/17 18:02:16 mdw
- * New multiprecision integer arithmetic suite.
