Fixing #46.

I don't see any warnings when I compile the Echo example for Teensy 3.5 (arm chip) or Teensy 2.0 (avr chip).

Which board and software are you using?

I don't think it's board-dependent (but I have Arduino Nano). Do you have all the warnings turned on? File > Preferences > Compiler warnings: All. If you use bare GCC, turn on either -Wall or -Wunused-variable.
