Well, FALSE can reasonably be assumed to be zero.  But there is
nothing to say (in the various standards for C, C++, or C9X) that TRUE
is necessarily one.  It is any non-zero number, including negative.

Make tests against FALSE by all means, but testing for 'TRUE' as a
specific value is asking for trouble.
