clang: 'auto' not allowed in function prototype #8

Hi

I'm trying to cross compile this for Android. Android NDK uses clang, and apparently it doesn't support auto in functions : https://stackoverflow.com/questions/30665506/auto-not-allowed-in-function-prototype-with-clang

Error log :

  ninja: build stopped: subcommand failed.

Is there an alternative to using auto and then get it compiled ? I don't know C++ really.
