65fea56f17cd614bc8908264df980a62e1931468vboxsync * Most compilers will convert divisions by 65536 into shifts, if signed
65fea56f17cd614bc8908264df980a62e1931468vboxsync * shifts exist. If your machine does arithmetic shifts and your compiler
65fea56f17cd614bc8908264df980a62e1931468vboxsync * can't get it right, add to this line.
65fea56f17cd614bc8908264df980a62e1931468vboxsync * mips compiler - what a joke - it CSEs the 65536 constant into a reg
65fea56f17cd614bc8908264df980a62e1931468vboxsync * forcing as to use div instead of shift. Let's be explicit.
