  * harbour/contrib/rddads/adsfunc.c
    * ADSREGCALLBACK() implemented using AdsRegisterCallbackFunction() instead
      of obsolete AdsRegisterProgressCallback(). This enables draw progress
      bar for both indexing and SQL query processing.
    ; implementation unchanged for old ADS versions (<= 6.1)
