No.  You can forget about finding a portable way to avoid using vararg.h
(or its improved ANSI incarnation, stdarg.h); there is *none*.  None.  NONE.
***NONE***.  There are a dozen different tricks people are fond of using,
and they all fail on an increasing number of machines.  (What makes you
think the parameters are pushed on the stack in any simple order, or
indeed that they are pushed onto a stack at all?)
