Varargs works fine on Pyramids.  You must, of course, constrain yourself
to use them in accordance with the manual, including avoiding things like

	for (va_start(ap); <cond>; <iter>) stmt;
	va_end(ap);

which `look fine' on a casual scan but are not in fact legal.  In fact,
va_start compiles to one statement on the 3B, but includes a left brace
and a declaration on the Pyramid.
