MSDN says:

    Number of the information node (the inode) for the file
    (UNIX-specific). On UNIX file systems, the inode describes the
    file date and time stamps, permissions, and content. When files
    are hard-linked to one another, they share the same inode. The
    inode, and therefore st_ino, has no meaning in the FAT, HPFS, or
    NTFS file systems.

I wonder if this might return non-zero for some relatively rare Win32
filesystems (say, an NFS share mounted via MS Services For
Unix). Perhaps it might be cleaner to consider a zero inode "unknown",
and therefore not equal to anything else?

grain of salt)
