Actually the exit; does nothing but throw this warning.

...\arduino_modified_sketch_800891\sketch_may17b.ino: In function 'void setup()':

C:\Users\DaD\AppData\Local\Temp\arduino_modified_sketch_800891\sketch_may17b.ino:9:11: warning: statement is a reference, not call, to function 'exit' [-Waddress]
      exit;

The exit(0) function would exit loop, disable interrupts and freeze.

That code is in loop(), not in setup(). Why does the compiler think it is in setup()?

I installed the Adafruit PWM Servo library (against my better judgement) and do not get any errors:
