  /* At least one file in any SDL/WinRT app appears to require compilation
     with C++/CX, otherwise a Windows Metadata file won't get created, and
     an APPX0702 build error can appear shortly after linking.
  
     The following set of preprocessor code forces this file to be compiled
     as C++/CX, which appears to cause Visual C++ 2012's build tools to
     create this .winmd file, and will help allow builds of SDL/WinRT apps
     to proceed without error.
  
     If other files in an app's project enable C++/CX compilation, then it might
     be possible for SDL_winrt_main_NonXAML.cpp to be compiled without /ZW,
     for Visual C++'s build tools to create a winmd file, and for the app to
     build without APPX0702 errors.  In this case, if
     SDL_WINRT_METADATA_FILE_AVAILABLE is defined as a C/C++ macro, then
     the #error (to force C++/CX compilation) will be disabled.
  
     Please note that /ZW can be specified on a file-by-file basis.  To do this,
     right click on the file in Visual C++, click Properties, then change the
     setting through the dialog that comes up.
