f78b12e570284aa8291f4ca1add24937fd107403vboxsync * Most compilers will convert divisions by 65536 into shifts, if signed
f78b12e570284aa8291f4ca1add24937fd107403vboxsync * shifts exist. If your machine does arithmetic shifts and your compiler
f78b12e570284aa8291f4ca1add24937fd107403vboxsync * can't get it right, add to this line.
f78b12e570284aa8291f4ca1add24937fd107403vboxsync * mips compiler - what a joke - it CSEs the 65536 constant into a reg
f78b12e570284aa8291f4ca1add24937fd107403vboxsync * forcing as to use div instead of shift. Let's be explicit.
