    Cygwin: Map ERROR_NO_SUCH_DEVICE and ERROR_MEDIA_CHANGED to ENODEV
    
    If a removable (USB) device is disconnected after opening its raw
    device, R/W attempts fail with ERROR_NO_SUCH_DEVICE(433).  If the
    raw device of a partition is used, ERROR_MEDIA_CHANGED(1110) is
    returned instead.  Both are mapped to ENODEV(19) because <errno.h>
    does not offer a value which better matches ERROR_MEDIA_CHANGED.
