Just a minor thing, but a huge outcome. All the other jni related functions already have those flags, but the nativeInit function lacks them - so it might be stripped away.

When generating a signed app with SDL 2.0.3 an issue comes up, watching at the Error Log points out that the issue lies in the src/main/android/SDL_android_main.c where the process name is defined as "SDL_app", this name turns into an erroneous name so it should be changed to "app_process"
C++ is a bit of a minefield on Android. Much functionality still doesn't work, and Android can't decide on which C++ standard library to use, so it provides 3 different ones, all of which are incompatible with each other. (It looks like clang is coming too which will add a new compiler and a 4th standard library.)
As middleware, SDL might be distributed as a binary and intermixed with other projects already using C++. If C++ is intermixed in a bad way, bad things will happen. Removing dependencies on C++ will avoid this problem and downstream users won't have to worry/care.
