FreeBSD 10.0 compile error

Created by: Slechtvalk

Hi,

I got the following compile errors when compiling your new API on FreeBSD 10.0 (using clang) :

`Scanning dependencies of target ArduinoJSon [ 76%] Building CXX object software/extern/json/CMakeFiles/ArduinoJSon.dir/ArduinoJson/src/Arduino/Print.cpp.o

Is this a bug, or a compile issue I have?
