I checked the used versions - as I already wrote the used arduino-IDE is 1.6.8. But due to the case that I used 1.8.0 before and downgraded the board definition by "Board manager" the board definition is 1.6.11 (if you down/upgrade by BoardManager you can find the files in dir "C:\Users...\AppData\Local\Arduino15\packages\arduino\hardware\avr\1.6.11"
I added my own definitions to board.txt (because I use 2AA Battery node -> https://www.openhardware.io/view/10/My-Slim-2AA-Battery-Node)
here my quick and dirty source - have to clean up if it works as expected:
