There is at least one network where DOS function 0x60 (get canonical path)
returns a garbage string and no error. I can't remember the network, but
we did encounter this problem in our "cp" program. The code to canonicalize
a pathname is not that complicated, about 60 lines of C.

And under PC-NFS, there is no way to determine if files are the
same if they are linked together on the UNIX file system.
