Notes, presented in no particular order:
	1) I don't know if this is a GCC under Unix specific question (which
	   is my primary/only focus) or if it relates to all C compilers
	   and/or all platforms.
	2) From what I can tell, there is a thing called varargs that is:
		a) More powerful than stdarg
		b) No longer documented
		c) No longer supported
		d) Not (as) portable
	3) Here's the code that I have (I wrote it and it works fine):
/* Find the max of a list of ints, 0 marks the end of the list */
#include <stdarg.h>
int max(int n, ...)
{
   va_list ap;
   int maxnum = n;

   va_start(ap, n);
   while ((n = va_arg(ap, int)))
	if (n > maxnum)
	     maxnum = n;
   va_end(ap);
   return maxnum;
}

	4) Question: From what I can tell, stdarg has the following
	   limitations:
		a) No way to tell how many args there are.  I.e., you have
		   to have some kind of marker for the end of the list.  If
		   you try to access more args than are passed, strange and
		   bad things will happen.
		b) You have to have at least one fixed arg.  This causes it
		   to fail the "acid test" - namely, "Can I write a wrapper
		   around printf?"  This is mentioned in the man page
		   ("man stdarg" on a Linux system).

So, have I got this all right?  In particular, I am curious about the
questions raised in #4, and wondering if it is possible to use varargs
(which I can tell exist, from the header files, but I can't find docu on)
