        This working version is believed to be stable, but
        we have not run our full regression-test suite.

   This version adds implementations of structures <tt>Int64</tt> and
   (inofficially) <tt>Word64</tt>.



      <li>Added <tt>structure Int64</tt>, an implementation of
      non-native 64-bit integer arithmetic.</li>

      <li>Added an inofficial <tt>structure Word64</tt>, an
      implementation of non-native 64-bit word arithmetic.
      The structure is inofficial in the sense that:
	<li><tt>LargeWord</tt> is still the same as <tt>Word32</tt></li>
	<li>the implementations of <tt>toLargeWord</tt>,
	<tt>toLargeWordX</tt>, and <tt>fromLargeWord</tt>
	are dummy placeholders that raise an exception when called.</li>
    Neither Int64 nor Word64 are very efficient at the moment as they
    do not rely on native machine support for 64-bit arithmetic
    (and not even on such things as 32-bit multiplications with 64-bit
      <li>Added a few primops in support of the implementation of
      64-bit arithmetic mentioned above.</li>
