yes - renaming was what I had in mind to make it simpler to adjust the
environment list (otherwise you're constantly reallocating it - bear in
mind that it's initially not derived from malloc).
I've also read that 'environ' is not necessarily supported on all platforms
(Unix-style that is), so it's something more for the configure script.
