Platform specific- INT_MAX doesn't have to be 011111....1111. It
can be all 0's, if the platform is braindead. So that's undecidable
without more knowledge.
In general, with bitwise operators, you need to be sure about the
bitwise layout of your types. It does seem odd to use INT_MAX instead
of (~0) for a mask, but who knows what the intent is.
that was meant to be (~0>>1) of course.
