This is all quite correct.  It's been about two years since I had to use
ZEUS, thankfully, but for as long as I was in contact with it there
was no working varargs.h by Zilog.  (They thoughtfully supplied a
PDP-11 one.)  After getting heartily sick of every second piece of
software I tried to port to the thing breaking where it tried to
do variadic routines, and being tired of re-inventing the wheel
each time, I did varargs.h for the ZEUS.  It works.  If anyone
is interested, I'll post it to net.sources (it's only short, and
is also a monument to human braindamage -- what I had to go through
must be seen to be believed).
