You'll need to upgrade your IDE (if you're using the Arduino IDE).
Since version 1.5.8 of the IDE, GCC has been version 4.8.1. However, you'll need to manually enable it with the command line switch you were using.
If you grab the latest (1.6.2 and above, currently 1.6.9) C++11 is enabled by default.
