No need to declare the real argv anything more than it is right now.
I've moved your code to main() and added a bit of code so that the
argv copying is also done when sizeof(Argv) < __INITIAL_POINTER_SIZE/8
That was easy enough. I did a little bit of renaming so the rest of
main() would accept this new variable.

Naah... this is only needed in makeapps.com, as far as I can tell,
and it wouldn't be too hard to have a spot in the code simply try the
following command:
CC /POINTER_SIZE=64=ARGV NL:
and see if that gives back a condition code from DCL (facility number
3) or the compiler (facility number something different ;-)). It's
really just one or the other and is pretty easy to do.
Getting to it.
Cheers,
Richard
