I *think* that the C spec doesn't specify the result

I don't know about earlier versions, but the C99 spec
guarantees that they will return 1 if true and 0 if
not. The logic for determining whether something is
true or false still boils down to "zero means false,
nonzero means true," obviously, but the operators
themselves can only return 1 or 0.
Cheers,
