Quintus to Gnu Prolog conversion

We have been running our parser with Quintus Prolog and wish to replace Quintus with Gnu Prolog. But the Gnu compiler finds syntax errors such as the ones below. I shall warmly appreciate suggestions for correcting the errors, and any information where a comparison of Gnu Prolog syntax to Quintus Prolog can be found.
