    windows: remove st_dev test from SAME_INODE
    
    As reported "st_dev is the drive number, so on D: it is 3 and the
    guard passes.  Every file on the drive then compares equal to every
    other file."
    
            * same-inode.h (SAME_INODE): Do not test st_dev on windows to
            validate st_dev/st_ino comparison.
