NO!  DON'T TOUCH THAT... <sound of muffled explosion>

This is true on *some* machines, but is certainly false on other
machines.  There are a couple reasons why.  One is that the C language
doesn't define things to be done this way, so anybody who wants to
push right-to-left can do so as long as their compiler works.  I'm not
sure that any modern compilers do this *currently*, but (a) there have
been in the past and (b) there probably will be again.  Another good
reason why this isn't portable is that some machines have stacks that
grow *up* and some have stacks that grow *down*.  Finally, there is no
guarantee that the arguments, even arguments of the same size, will be
in contiguous memory.

How to do this portably?  Start with <varargs.h> or <stdargs.h>.
Then go read <14015 at mimsy.UUCP> (comp.lang.c, 16 Oct 1988).
