    We want to avoid compilation and, even more perniciously, link errors if
    the user code includes <windows.h> before include wxWidgets headers. These
    error happen because <windows.h> #define's many common symbols, such as
    Yield or GetClassInfo, which are also used in wxWidgets API. Including our
    "cleanup" header below un-#defines them to fix this.

    Moreover, notice that it is also possible for the user code to include some
    wx header (this including wx/defs.h), then include <windows.h> and then
    include another wx header. To avoid the problem for the second header
    inclusion, we must include wx/msw/winundef.h from here always and not just
    during the first inclusion, so it has to be outside of _WX_DEFS_H_ guard
    check below.

    In C++20 operations on the elements of different enums are deprecated and
    many compilers (clang 10+, gcc 11+, MSVS 2019) warn about combining them,
    as a lot of existing code using them does, so we provide explicit operators
    for doing this, that do the same thing as would happen without them, but
    without the warnings.

    Low word style bits is class-specific meaning that the same bit can have
    different meanings for different controls (e.g. 0x10 is wxCB_READONLY
    meaning that the control can't be modified for wxComboBox but wxLB_SORT
    meaning that the control should be kept sorted for wxListBox, while
    wxLB_SORT has a different value -- and this is just fine).
