f0ab104f070bc7f569404826fea1828ed985638cvboxsync * Most compilers will convert divisions by 65536 into shifts, if signed
f0ab104f070bc7f569404826fea1828ed985638cvboxsync * shifts exist. If your machine does arithmetic shifts and your compiler
f0ab104f070bc7f569404826fea1828ed985638cvboxsync * can't get it right, add to this line.
f0ab104f070bc7f569404826fea1828ed985638cvboxsync * mips compiler - what a joke - it CSEs the 65536 constant into a reg
f0ab104f070bc7f569404826fea1828ed985638cvboxsync * forcing as to use div instead of shift. Let's be explicit.
