45e9809aff7304721fddb95654901b32195c9c7avboxsync * Most compilers will convert divisions by 65536 into shifts, if signed
45e9809aff7304721fddb95654901b32195c9c7avboxsync * shifts exist. If your machine does arithmetic shifts and your compiler
45e9809aff7304721fddb95654901b32195c9c7avboxsync * can't get it right, add to this line.
45e9809aff7304721fddb95654901b32195c9c7avboxsync * mips compiler - what a joke - it CSEs the 65536 constant into a reg
45e9809aff7304721fddb95654901b32195c9c7avboxsync * forcing as to use div instead of shift. Let's be explicit.
