 * History:
 * V0.3   20-Jul-98
 *        Differentiation between 603 and 604. Now, scheduling takes
 *        place with regard to the real PowerPC architecture.
 * V0.1   10-Jul-98
 *        vscppc seems to be stable enough, after some tests.
 *        However, it still needs a lot of fine tuning.
 *        A differentiation between the PPC CPUs (603e, 604e) is missing.
 * V0.0   09-Jul-98
 *        File created.
