import core.sys.windows.windows;

extern (Windows)
int WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int
iCmdShow)

    version(OK)
    {

The error seems to go away if you either introduce a try/catch or an import
into any 'std' module.

Obviously the chances of having no imports and no try/catch in a module
implementing WinMain are very low, but the behavior is strange.
