By returning -1, I give you the chance to test for the existence
of a routine, and take some action if it doesn't exist.
You can at least issue your own error message and shut down
gracefully. Maybe most people would prefer to just fail 
on the spot. In any case, if you continue, and use the -1 in a call_proc 
or call_func, you'll get an error message. I think it's too late 
to change this now, and I don't think there
are really "major headaches" in most cases.
