Unable to get multiple answers using Pl_Query_Next_Solution

[Lindsey Spratt]

I have a simple case where Pl_Query_Next_Solution returns only the 
first solution, when there should be two solutions.

Gprolog version 1.2.16, on Mac OS X 10.2.3.

In my modified version of gprolog (using the patches I sent you, 
compiled with debugging turned on), this produces the correct answer.
