*AHEM*  No, in certain *implementations* of the C language arguments are
placed onto the stack in reverse order....

In other implementations some of them are stuffed into registers.

The closest things to a portable way of doing a function taking a
variable number of arguments are:

	1) "varargs" - present on many (most?) UNIX systems' C
	   implementations, and possibly on other implementations as
	   well (see VARARGS(n), for some value of "n", in the UNIX
	   documentation; if you don't have UNIX, look somewhere else).

	2) "stdargs" - specified by ANSI C, so probably present in many
	   microcomputer implementations.
