See the C FAQ, question, 5.17:

    http://c-faq.com/null/machexamp.html

See also questions 5.16 and 7.31.

This part of the FAQ probably hasn't been updated for over fifteen
years, and the machines mentioned are no doubt museum pieces by now.
I don't know if any current machines represent NULL with non-zeros.
Any such machines are probably far out of the mainstream, and will
likely never attempt to run Evergreen.

Nevertheless I don't like making needlessly non-portable assumptions,
especially when those assumptions are neither obvious nor documented.
You may of course not wish to be as pedantic as I am.
