I cannot comment on main() being handled differently than
other C functions. I was just quoting my old copy of K&R.

I don't understand what you mean with "no version of C has
ever permitted", given that my C compiler doesn't complain.

WRT return value to the environment I'd expect any random
or arbitrary value being returned in case that non had been
explicitly specified to be returned.

If I want a defined exit status (which is what I usually
want) I specify 'int main (...)' and provide an explicit
return statement (or exit() call).
