It is. Actually it's surprising gcc didn't tell me that casting from
const uint8_t * to void * and then writing to the pointer is not a
Perhaps those structs should be made global and added to an atapi.h
header? This way you can avoid (void *) casts.
(In fact, there's a scsi.h file in the Win32 free header files waiting
to be lifted in QEMU... unfortunately, the similar atapi header file has
not been written yet though I think it is in the Windows DDK).
