- *
- * $Log: mpx-ksqr.c,v $
- * Revision 1.7  2002/10/09 00:36:03  mdw
- * Fix bounds on workspace for Karatsuba operations.
- *
- * Revision 1.6  2000/10/08 15:48:35  mdw
- * Rename Karatsuba constants now that we have @gfx_kmul@ too.
- *
- * Revision 1.5  2000/10/08 12:11:01  mdw
- * Use @mpx_ueq@ instead of @MPX_UCMP@.
- *
- * Revision 1.4  2000/07/29 17:04:02  mdw
- * Remove useless header `mpscan.h'.
- *
- * Revision 1.3  2000/06/17 11:42:54  mdw
- * Moved the Karatsuba macros into a separate file for better sharing.
- * Fixed some comments.  Use an improved technique so that all the
- * operations are squarings.
- *
- * Revision 1.2  1999/12/13 15:35:01  mdw
- * Simplify and improve.
- *
- * Revision 1.1  1999/12/11 10:57:43  mdw
