Expressed this way, the answer is very simple:  you can't do this in C in
any portable way.  (There is no guarantee that you can do it even in an
unportable way.)  C simply does not give you the ability to build argument
lists yourself.  There are a few kludges for awkward cases like printf,
but no general primitives.
