Okay, did some Google'ng in groups and found messages from 1996 on this.
I just changed the XS code to declare argv as 'char * &argv'. I did see
the example in the XS_CookBookA and several examples on how to put the
array on to the stack, including Nick's post from May(I think?). Anyway
sorry to bother, I should have searched groups earlier. I did do a
Google and perl-xs list search though. =8^)
Thanks,
STH
