SDL_winrt_main_NonXAML.cpp, placed in the public domain by David Ludwig 3/13/14
#include "SDL_main.h"
#include <wrl.h>
/* 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.

is compiled with C++/CX enabled (via the /ZW compiler flag).
