It's a bug in the header, because it's polluting the namespace with
unnecessary usage of "Status" as parameter names in prototypes.  The
header should use __status__ or drop them entirely.

What you could try is either one of

- Change the order of the header files, so that the windows headers
  are included before the private header defining Status.

- Or, prior to including the Windows headers, push the macro and
  undefine it, after including the windows headers, pop the macro:

    #pragma push_macro ("Status")
    #undef Status
    #include <windows.h>
    #pragma pop_macro ("Status")

- Or, you could not include windce.h at all if you don't need any of it:

   #define __RPCDCE_H__
   #include <windows.h>
   ...

Apart from that, the header should be fixed in Mingw-w64.
