The integer value -0 has to be represented the same as 0, namely all 0 bits.
To write a "minus zero" the simplest thing is to write ~0.  Of course, the
fact that your code is dealing with an explicit minus zero already makes it
dependent on ones-complement architecture.  (I don't know how to do the
equivalent thing on a sign/magnitude architecture; there may be a way.)
