Bear in mind that a==b returns an integer - zero if a!=b, nonzero
(usually 1) if a==b.

Thus a==b==c returns 1 is a==b and c is true, or a==b and c is false.
If I've got the associativity right.

a==b==c==0 does something similar. Probably inverts the entire above
sentence - checking if something is zero is the same as logically
inverting it...
