//---------------------------------------------------------------------------

  History of changes:
  ===================

20 JUL 2002 - neopop_uk
=======================================
- Cleaned and tidied up for the source release

24 JUL 2002 - neopop_uk
=======================================
- Fixed S flag in "RRC (mem)"

25 JUL 2002 - neopop_uk
=======================================
- Removed unneeded Long mode from EX.

28 JUL 2002 - neopop_uk
=======================================
- Improved the LDIR/LDDR/CPIR/CPDR instructions so that they
	finish with the correct register settings, even if there is
	a memory error.
- Converted DIV/DIVS to use the generic function

16 AUG 2002 - neopop_uk
=======================================
- Replaced 'second & 7' with 'R', clearer, faster - and for some reason
	more accurate... oh well!
- Fixed V flag emulation of INC/DEC, fixes "Cotton" menus

21 AUG 2002 - neopop_uk
=======================================
- Fixed "RR (mem)" - It was actually the [REG] version that hadn't been
	changed to use memory accesses!

30 AUG 2002 - neopop_uk
=======================================
- Fixed "DIV RR,(mem)" in long mode, wrong operand size.

04 SEP 2002 - neopop_uk
=======================================
- Fixed GCC compatibility.
