This delta http://hg.libsdl.org/SDL/rev/a15821a3471f means that the minimum API level supported is 9, as the EGL/egl.h file is not present in API level 8.
Unfortunately this drops support for (currently) 9% of devices (http://developer.android.com/about/dashboards/index.html). I opted to just copy the required EGL defines into SDL_android.cpp:

This seems to work fine building for API 8. Tested on Android 2.2.2.
Not sure I’m recommending this as a change to the SDL source, but it might be useful to someone.
Cheers,
