Seriously: why *bother* prototyping these functions, then?  Is it just
an escape to get through a `strong typing' tool?  I really don't see
that a prototype that says ``anything allowed''  buys _anything_.

It's also the case that using the ellipsis in a prototype can result
in a less-efficient argument-passing sequence at run-time, on some
architectures.
