Even if you treat arguments as being pushed by the caller/popped
by the callee, you have an ambiguity.  Is the order of the arguments
that of the callers (I push the first argument first) or the callees
(the first argument is the one I pop off first).  Certainly variable
number of arguments is easier handled by the first, but they are
forbidden in ANSI C anyway.

The order is undefined not just because stack arguments may be placed
in either order, but because the call linkage is not defined by the
C language at all.  An implementor is free to place all the args in
an envelope and mail them to the subroutine as far as the C standard
is concerned.
