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.
