/*
different result depending on whether constant is on left or right side
Different results, depending on whether constant is on left or right side.
The optimizer sometimes makes code that executes the right-side expression
as eight bits; but then, tests it against the left-side zero as 16 bits.
The high-byte is garbage; therefore, that test might, or might not, work.
It depends on the platform and the amount of optimization.
