1641a90c3f - .win32_dll_plugin_target still needs $(GUI_LINK_OPTS) since there is some 
gui-dependent stuff in main.cc (SDL redefines 'main', win32 console creation
  for SDL and wxMSW).

4f2af797b5 - library dependencies in the main bochs binary and the gui plugins fixed. 
These changes are based on the SF patch #742670. It did not work with
  plugins disabled.

Here is the descriiption of patch #742670:

the library dependencies (see objdump -p file) in the
main bochs binary and the gui plugins are wrong:

- the gui plugins don't depend on their respective gui
libraries
- the main bochs binary depends on all the gui libraries

this doesn't seem much of a problem, since the needed
libraries are loaded anyway, but it's problematic when
building packages for binary distribution of bochs.

in Debian, the package building tools will set package
dependencies according to the library dependencies of
each file, so the result is:

- the main bochs package depends on all libraries. this
includes libwx, libsdl, libncurses and xlibs.
- the indivudual plugin packages don't depend on any
gui library

so when a user wants to run bochs with the curses gui
and installs the bochs-curses package, he/she will be
forced to install Xfree86, WxWindows and GTK+ on
his/her system.

the attached patch fixes the problem by moving the
linker flags related to GUI libraries to the right
makefile (gui/Makefile.in)

a510ce56ee Add configurable option to never completely fill the buffer rings. 
It's not clear what the correct behavior is in that case, (we
clearly don't currently handle it correctly) so
simply avoiding it is the easiest thing to do.  As such, this
option is ON by default.

3a788ddcf4 - char width switch feature (8 / 9 pixels) prepared for all display libraries 
and implemented in SDL
  * sequencer controller register 0x01 bit 0 controls the width of the characters.
    This value is used to calculate the screen width.
  * attribute controller register 0x10 bit 2 controls the appearance of graphics
    characters (ASCII 0xC0 - 0cDF). A change of this value forces a charmap update
    to rebuild the font bitmaps.
  * the SDL display library uses the new feature described above
  * the other display libraries recalculate the screen width, since they are using
    a fixed font width of 8 for now.
- VGA: attribute controller register 0x10 bit 2 (enable_line_graphics) does not
  switch the palatte in CGA mode

a17d06abcb Optimized the main cpu loop iCache checks to remove a redundant 
check.

Commented out a number of instances of invalidate_prefetch_q(),
for branches which do not change CS since the EIP window mechanism
takes care of validating that EIP lands in the current page or not
in the main cpu loop anyways.

Fixed a couple cases (v8086 mode and real mode) of loading CS where
the EIP page window was not invalidated in segment_ctrl_pro.cc.
That may fix some aliasing problems reported before (OS2).

    - growable : growing file
    - volatile : flat file with volatile redolog
    - z-undoable : gziped flat file with commitable redolog
    - z-volatile : gziped flat file with volatile redolog
  A new "bxcommit" utility can merge commitable redologs to

b3d16a48ef - apply another speedup patch from Conn Clark. 
Notes from the author:
Here is another one of my speed up patches. Unlike my previous speedups
this one will help more platforms than just X86. It cleans up the Data
Xfer instructions. Since the Data Xfer instructions are the most often
executed instructions it gives a noticable boost in speed. The basic
optimization technique was to eliminate intermediate variables and pass
a pointer to the final destination or original source to the
read_virtual_whatever and the write_virtual_whatever functions.

a6dd6deaf5 - apply patch from James E. Flemer: 
I've got a game that uses OPL2 functions.  It's still not
working yet, but this patch brings it closer.  Using Jeffrey S.
Lee's "Programming the AdLib/Sound Blaster FM Music Chips (Ver
2.0)"[1] as a reference, I found an inversion of the OPL timer
masks in the sb16 code.  Without this patch, the emulator uses
the wrong bits for masking, and completely botches the flags
register (note the bitwise AND vs OR).

1e71c9e56e Merged patch-unallowed-lock-cases patch. 
According to the Intel manuals:

  The  LOCK  prefix  can be prepended only to the following instructions
  and  only  to  those  forms  of the instructions where the destination
  operand  is  a  memory operand: ADD, ADC, AND, BTC, BTR, BTS, CMPXCHG,
  CMPXCH8B,  DEC,  INC,  NEG, NOT, OR, SBB, SUB, XOR, XADD, and XCHG. If
  the  LOCK prefix is used with one of these instructions and the source
  operand  is a memory operand, an undefined opcode exception (#UD) will
  be  generated. An undefined opcode exception will also be generated if
  the  LOCK  prefix  is used with any instruction not in the above list.

 Checking of the LOCK prefix done in fetchDecode state and not overloads
 Bochs's execution.

* returned back `unsigned BX_CPU::which_cpu(void)` function

* added BX_CPU_ID parameter for
	BX_INSTR_PHY_READ(a20addr, len);
	BX_INSTR_PHY_WRITE(a20addr, len);

d4575083a7 - add performance patch contributed by Conn Clark. 
It uses special gcc attribute regparm, available on gcc3.2 on x86.
  I get about 7% increase when booting windows 95.
  The patch still need some integration work before being included
  in the main code.

f25a3df39b - added minimal USB support (patch from Ben Lunt <fys@cybertrails.com>, updated 
and improved by Christophe Bothamy and Volker Ruppert)

Comment from the author:

Attached is a "patch" file detailing what you need to do
to add USB support (UHCI only for now) to your existing
Bochs (2.0.xx) source code.

I use Win32 and VC++ but the source and modifications
should be platform and compiler independant.

Please let me know if this patch some how breaks the
build process of your compilation (Bochs 2.0.0 or above
only).

I would also like any feedback on how this code works
(or doesn't work) on your platform and within your
images. If you explain in as much detail as you can on
how it did or did not work, I will try to add to the source
to help it work on all platforms and images.

b2622c5d04 Temporary tweak to reinstate a change that disappeared when sse2.cc was removed. 
The 64 bit variant of MOVNTI was not decoded.  The proper fix for this is to work on
fetchdecode64.cc to call a 64 bit variant of SSE instructions or fail it with a
invalid op.  A careful check needs to be done with the AMD manuals to determine if
there are any other SSE instructions that have a special 64 bit decoding.

Kevin Lawton
87d648682e Code cleanup. Moved the interrupt redirection instrumentation 
into the host-specific files and wrapped access to them
  with atomic operations since that's a structure global to
  all the VMs.  I think all the other globals are SMP clean
  since they are only written once during module init time,
  and read thereafter my all VMs.
Renamed all host OS specific functions to hostOS*().  All host
  independent functions to host*().
I'd like to rename all monitor space functions to mon*() next.
