-- The error:

In "PROT_ASSP.h" I obviously erroneously referenced an array like this:

  extern const word8_a ASSP_z_Num [] = {};

In the "PROT_ASSP.c" I have declared this array:

  static const word8_a ASSP_z_Num [] =
      {
          2, // ASSP_ANSWER_TIME_OR_IDLE_CURRENT_WANTED_a
          2, // ASSP_RELAY_AND_BEEP_a
          2, // ASSP_READ_DETECTOR_STATUS_a
          2, // ASSP_READ_CODE_a
          2, // ASSP_READ_TOTAL_STATUS_a
          2, // ASSP_RESET_a
          2, // ASSP_RETRANSMIT_LAST_ANSWER_a
          2, // ASSP_SIMULATE_ANSWER_a
          2, // ASSP_WRITE_DETECTOR_STATUS_a
          2, // ASSP_IO_a
          2  // ASSP_RESYNCH_a
    };

word8_a is:

  typedef unsigned char word8_a;

-- I'll now have to find out how to do it correctly!
