It is nothing to do with the headers. There is no difference in result between SDL 2.0.3 headers or Sathya's. Not surprising since the app just calls a few SDL functions and passes a few enums.
The problem was that the entry to my native OpenGL ES application is SDL_main(). SDL either provides a main() which calls SDL_main() or a define that changes SDL_main() to main() depending on the platform. Neither of those things are happening in this case with either set of headers so there is no main() and so Module['_main'] is empty in the compiled JS. I have not yet investigated exactly why. Once I figure it out I'll file an issue. The upstreamed code needs to ensure SDL_main can be used just like in native. If I change the name to main() everything works. It even works in IE11!!!!! It took me half a day to find this due to issue 2133 <https://github.com/kripken/emscripten/issues/2133>, which confuses the debuggers about line numbers, additional issues with both Firefox debuggers and the obscure connection between loading the document and getting to the code in the generated .js file. Problems with the FF debuggers are: * The default debugger fails to see MyApp.js. It only shows MyApp.html. * Firebug's script runs for so long that the stop/continue pop-up appears. Even if you click stop, it keeps running. It is possible these are related to issue 2133 as well.
