I can absolutely confirm this with VS2015, Visual Micro and MySensors 2.1.1. This is clearly a kind of merging, that is done by Visual Micro.
All includes have to be made BEFORE the first line of code is executed. The initialization of your
SENSOR_ANALOG_PINS array is such a line of code.
Just posting it to keep it visible and well-scored at search engines, as this is SOLVED and works fine. Thank you!
