/** \def DEBUG
  Enable debug output generally and some additional M-codes.

  Individual flags are enabled at runtime using M111 (see gcode_process.c) or
  by modifying the presets here.

  WARNING: enabling some or all of these is done can produce /heaps/ of extra
  output. This extra output will break most host-side talkers that expect
  particular responses from firmware such as RepRap Host or ReplicatorG. Use
  with serial terminal or other suitable talker only.
