Oh?  On what machine is (1==1) equal to 0, or (1==0) not equal to 0?  In
section 7.6 (Relational operators, Appendix A - C Reference Manual from
K&R's The C Programming Language), it explicitly states that the logical
operators all yield 0 if the relation is false and 1 if the relation is
true.  Nothing is mentioned about possible variations due to implementation
machine differences.
