zoo files extraction (Users)

Hi! Turns out that zooext.c, msdos.c and dosfns.h work with a signed 16-bit cluster size. This overflows when clusters are 32 kB or larger, making ZOO believe that your disk is full :-p

Question: Are you aware of any OTHER apps with the same bug? After all, HIMEM even has a command line option to limit reported XMS to less than 32 MB because multiple apps have a similar overflow in their XMS handling :-p
