The following command, with the main() function defined in DBInput.c,
when executed in koud/proj gives a Prolog interpreter (output in file g)
which works just fine. Yet the same command in koud/newproj does not
do it....

g++ -o g Sub.o SingleSub.o Term.o TermInput.o temps.o Cond.o BoolExp.o Fun.o FunTree.o Function.o Structure.o Error.o Constructor.o Rule.o DB.o RuleInp.o DBInput.o VPArray.o Parameter.o
