      On gcc 7 the new -Wimplicit-fallthrough option was introduced which produces warnings about switch cases that can fall through.

      The easiest way to silence these warnings is to add the comment /* Falls through. */ for those cases. More information here [0]

      Attaching the stderr output from compilation from the master branch.
