b9a21c3c91c47e090316e28d759194e46628ed49vboxsync * Most compilers will convert divisions by 65536 into shifts, if signed
b9a21c3c91c47e090316e28d759194e46628ed49vboxsync * shifts exist. If your machine does arithmetic shifts and your compiler
b9a21c3c91c47e090316e28d759194e46628ed49vboxsync * can't get it right, add to this line.

b9a21c3c91c47e090316e28d759194e46628ed49vboxsync * forcing as to use div instead of shift. Let's be explicit.
