При режиме совместимости delphi все компилируется без ошибок. В режиме objfpc компилятор выдает следующие сообщения:
oraconnection.pas(33,17) Error: There is no method in an ancestor class to be overridden: "TOraConnection.PrepareStatement(TSQLCursor, TSQLTransaction, ShortString, TParams)"
oraconnection.pas(45,17) Error: There is no method in an ancestor class to be overridden: "TOraConnection.UpdateIndexDefs(var TIndexDefs, ShortString)"

В модуле ibconnection.pp используется режим совместимости objfpc, модуль компилируется без ошибок?!
