WARNING: C++11 support is required for compiling mini_racer. Please make sure
you are using a compiler that supports at least C++11. Examples of such
compilers are GCC 4.7+ and Clang 3.2+.
If you are using Travis, consider either migrating your build to Ubuntu Trusty or
installing GCC 4.8. See mini_racer's README.md for more information.
