You can use clang_win_ignore_z7.patch. Clang should probably fix the
parsing code to ignore or handle the Z7 flag.
About the defines/options i can add them to toolset initialization.
At the moment it is probably easier to add them to user-config to get
started. About the compatibility flag you can pass vc10, vc11, vc12. It
adds the -fmsc-version command line parameter, as command line help
suggested it would not set _MSC_VER otherwise.
