You _can_ add predicates to the TurboProlog .LIB, but because of the
.SYM/project restriction, all .LIB predicates must be written in C!
I haven't tried, but you might get away with coding the predicates in
prolog and declaring them as global predicates with "language c", but
since you will want them in a module (not the root, which would have
the goal), and since modules require the "project" specification, I
would expect the .SYM to once again get in the way.
