Very logical in fact. 0 is NO bit set in any given size of boolean data 
type, -1 means ALL bits set on that same size boolean data type. And a 
check on TRUE or FALSE, can easily be done with checking the sign flag 
of a processor rather than doing actually any bit fiddling (at least on 
those CPUs that I am familiar with).
