The directory or file timestamp would never change from the viewpoint of
the client, then. If the directory reading routines were made to only
lstat, then the only time infomation would be made available would be after
a file was opened to do an fstat.

But...until you stat the links to get the stat info on the target of the
link, you don't know whether it's a directory or a file. How would
dos_mode() set the mode correctly from make_dir_struct() for the reply to
the client? Wouldn't the client display incorrect info (in, for instance,
FileManager) if a link is a directory but information is not returned to
that effect so a file icon is create rather than a directory icon?
Please pardon if I just haven't looked at the code or protocols enough yet.
