RFM69 library warnings

[jbeale]

The code works, so I guess the warnings I see from the Arduino 1.0.5 compiler (avr-g++.exe (WinAVR 20081205) 4.3.2) aren't a big deal. But is this something that could be cleaned up?

I got 1.0.5, didn't get those warnings, but they are legit.
Fixed now, thanks.

By default the Arduino IDE does not display compiler warnings. If you go to File->Preferences and check "Show verbose output during compilation" then it will.
