1ae23ad935 - MONITORX/MWAITX: It is possible that MWAITX wakeup from timed mwait but APIC timer was still not reset. 
A corruption would happen if MWAIT is called again to setup the timer while it still running from previous time.
  Also spurious wakeup could possibly happen as timer will send wakeup when it stops counting.

32c7c3815a Display lib options 'cmdmode' and 'gui_debug' are now ignored by the wxWidgets port. 
Using a bochsrc config designed for another gui no longer causes a BX_PANIC for unknown option.

Close cdrom image file on eject (#145)

eject. This left the handle open while Bochs was running, not allowing
the image file to be modified.

591e2aa79f bugfix: when CET was not compiled in the emulation behavior of non-CET CPU was altered 
CET 'change' some x86 behavior
For example EPTP[7] become not-reserved and write to it not fail anymore
VMX doesn't check error code for CP exception if CET is enabled
These behaviors these changed even when CET was not compiled in

6aa399e9eb Added x64 configuration for the VS2019 plugins workspace (fixes issue #8). 
Since VS2019 didn't copy all settings from win32, manually editing all files
was necessary (adding OutDir/IntDir stuff).
