>   Since the ESQL support package creates some diagnostic printouts
   it may be interesting to redirect these messages towards any
   destination. This might be done by overloading the type
   Connection_Type of the GNU.DB.ESQL_Support.ODBC package and
   providing implementations of the Error, Warning and Connect 
   procedures.
