  * X-1.16       Camiel Vanderhoeven                             12-JUL-2008
  *      Fixed typo in new fp DO_LDT implementation.
  *
  * X-1.15       Camiel Vanderhoeven                             12-JUN-2008
  *      Support for last written and last read memory locations.
  *
  * X-1.14       Camiel Vanderhoeven                             14-MAR-2008
  *      Formatting.
  *
  * X-1.13       Brian Wheeler                                   27-FEB-2008
  *      Avoid compiler warnings.
  *
  * X-1.12       Camiel Vanderhoeven                             06-FEB-2008
  *      Check for FPEN in old floating point code.
  *
  * X-1.11       Camiel Vanderhoeven                             05-FEB-2008
  *      Only use new floating-point code when HAVE_NEW_FP has been defined.
  *
  * X-1.10       Camiel Vanderhoeven                             28-JAN-2008
  *      Better floating-point exception handling.
  *
  * X-1.9        Camiel Vanderhoeven                             25-JAN-2008
  *      Trap on unalogned memory access. The previous implementation where
  *      unaligned accesses were silently allowed could go wrong when page
  *      boundaries are crossed.
  *
  * X-1.8        Camiel Vanderhoeven                             21-JAN-2008

  *
  * X-1.7        Camiel Vanderhoeven                             2-DEC-2007
  *      Changed the way translation buffers work.
  *
  * X-1.6        Camiel Vanderhoeven                             08-NOV-2007
  *      Restructured conversion routines.
  *
  * X-1.5        Eduardo Marcelo Serrat                          31-OCT-2007
  *      Fixed conversion routines.

  *      Moved all data that should be saved to a state file to a structure
  *      "state".
