PLEASE!  EVERYONE!  I goofed!  Please don't send me anymore messages
showing me how to do this.  I know how to use prototypes and the
stuff from <stdarg.h> (or <varargs.h>) to get at the variable parameters.
I goofed because I asked the WRONG question.

The question I meant to ask was "How can you use prototypes for a function
which can accept ZERO or more arguments?"

There appears to be NO WAY to do this.

Since I asked the original question, I been informed that I should not
even be worring about the "ZERO or more" case because, in actual practice,
it never occurs.

I'm now mostly convinced that this is true, so my (intended) question is
moot.
