*
* Fix for SDL bug https://bugzilla.libsdl.org/show_bug.cgi?id=3437:
* The extra 'SDL_' was added to the start of each IID's name, in order
* to prevent build errors on both MinGW-w64 and WinRT/UWP.
* (SDL bug https://bugzilla.libsdl.org/show_bug.cgi?id=3336 led to
* linker errors in WinRT/UWP builds.)
