umentation callbacks - Configure and compile - Bochs now can be compiled as native Windows x86-64 application (tested with Mingw gcc 4.5.1 and Microsoft Visual Studio Express 2010) - Added ability to configure CPUID stepping through .bochsrc. The default stepping value is 3. - Added ability to disable MONITOR/MWAIT support through .bochsrc CPUID option. The option is available only if compiled with --enable-monitor-mwait configure option. - Determine and select max physical address size automatically at configure time: - 32-bit physical address for 386/486 guests - 36-bit physical address for PSE-36 enabled Pentium guest - 40-bit physical address for PAE enabled P6 or later guests - Update config.guess/config.sub scripts to May 2010 revisions. - Update Visual Studio 2008 project files in build/win32/vs2008ex-workspace.zip - Added Bochs compilation timestamp after Bochs version s
