Perhaps I should have said, "an idiomatic or hackerly fix." ;)

That works like a charm, Graham (and good grief, the resulting program
is fast!).  

I wonder, Felix, if it might be worthwhile to add a configuration
switch to chicken that lets you up the parameter limit.  I take it
that libffi doesn't care what that number is, as long as it's some
kind of number (we could add a note to say that the management is not
responsible for what might happen if you set that to one trillion ;)

Thanks again!
