In my opinion, it would be good enough to expand any
symbolic links (or aliases/shortcuts/whatever your platform
calls them) and check whether the pathnames are the same.

That won't always work (in the presence of mountings from
file servers, e.g.) but it can't be any worse than the
problems we already have with different names for the
same file.
