565fa8ea8e - another speed boost: when not using SMP, use
BX_CPU_C bx_cpu;
     BX_MEM_C bx_mem;
  and when more than one processor, use
     BX_CPU_C    *bx_cpu_array[BX_SMP_PROCESSORS];
     BX_MEM_C    *bx_mem_array[BX_ADDRESS_SPACES];
  The changeover is controlled by BX_SMP_PROCESSORS, but there are only
  a few code changes since nearly all code uses the BX_CPU(n) and BX_MEM(n)
  macros.
- This turns out to make a 10% speed difference!  With this revision,
  the CVS version now gets 95% of the performance of the 3/25/2000
  snapshot, which I've been using as my baseline.

97d681fb89 - integrated Don Becker's RFB gui, added it as a configure option,
and put it in the docs.

e61d00351f - merged BRANCH-smp-bochs into main branch. For details see comments
in BRANCH-smp-bochs revisions.
- The general task was to make multiple CPU's which communicate
  through their APICs.  So instead of BX_CPU and BX_MEM, we now have
  BX_CPU(x) and BX_MEM(y).  For an SMP simulation you have several
  processors in a shared memory space, so there might be processors
  BX_CPU(0..3) but only one memory space BX_MEM(0).  For cosimulation,
  you could have BX_CPU(0) with BX_MEM(0), then BX_CPU(1) with
  BX_MEM(1).  WARNING: Cosimulation is almost certainly broken by the
  SMP changes.
- to simulate multiple CPUs, you have to give each CPU time to execute
  in turn.  This is currently implemented using debugger guards.  The
  cpu loop steps one CPU for a few instructions, then steps the
  next CPU for a few instructions, etc.
- there is some limited support in the debugger for two CPUs, for
  example printing information from each CPU when single stepping.

a04c65e642 - new, partially implemented, lines in .bochsrc allow run-time choice of
what action to take on panic, error, info, and debug.  The lines don't
  have any effect quite yet because of an initialization order problem
  with the logfunctions.

e363f402ca - This implements a solution that lets any GUI take over handling of any
signal.  First, selection of the GUI should cause BX_GUI_SIGHANDLER to
  be defined in config.h.in.  Then, the GUI should define member functions
    Bit32u get_sighandler_mask ();
    void sighandler (int sig);
  The mask function returns a bitfield where one bit corresponds to each
  signal.  For any signal whose bit is set to 1 in the return value of
  get_sighandler_mask, the gui will control that signal.  When the signal
  arrives, bx_gui.sighandler(sig) will be called by bx_signal_handler,
  instead of the default behavior of that signal.

d2203e662f - added most of Todd's "term mode" patch. I didn't apply all of the signal
handling part, so I need to figure out how control-C's and control-Z's
  will get mapped into keystrokes.

different partitions in separate files.

e2a0ce5c03 - Applied patch based on one by Roland Mainz, 4/1/2001.
Panic-is-fatal patch, allows user to choose whether to crash on bx_panic()
  or just print a warning.  The default behavior is still to crash.

4e04f4cb58 - change all inline declarations to one of two macros: BX_C_INLINE or
BX_CPP_INLINE.  Then in config.h.in you can define these two as you
  wish.

a6ad4c3903 - Applied const64bit patch:
For compilers (such as Microsoft VC++) which don't allow "LL" after a
  constant to make it 64-bit, this patch declares all such constants as
  BX_CONST64(value).  Then in config.in, a switch called
  BX_64BIT_CONSTANTS_USE_LL controls whether the macro puts the
  LL's in or not.  Configure sets the macro, if you're on a platform
  that can run such things.

76bbd83325 - check for sizeof int*
- check for snprintf, strtoull
- check if empty structs allowed
- check for hash_map.h
- check for blank labels as in   void main () { int x=2; label: }
- if debugger, turn on disasm too
