st_ino; they always set it to zero. (Windows does provide a
meaningful st_dev.) Do not indicate a duplicate library in that
case. While there is no guarantee that a system that provides
meaningful inode numbers will never set st_ino to zero, this is
merely an optimization, so we do not need to worry about false
