/* On iOS SDL provides a main function that creates an application delegate
and starts the iOS application run loop.
If you link with SDL dynamically on iOS, the main function can't be in a
shared library, so you need to link with libSDLmain.a, which includes a
stub main function that calls into the shared library to start execution.
See src/video/uikit/SDL_uikitappdelegate.m for more details.
