You are correct, SVN doesn't support symlinks on MS-Windows. So, it
might well be that nothing is to be done on the Emacs side. But please
read the following...
> Does your port of SVN support symlinks?
FYI, my port is the collabnet one.

$ svn --version

It does not support symlinks to the extent that if there is a symlink in
the repo, then the symlink is not created by a chekcout in the work
area. Instead a plain file containing the link information is
created. However, if I create manually the symlink in place of this
file, then subsequent svn update won't overwrite it.
Now, here, we are not talking about a symlink in the repo, this is a
symlink created locally and which is not under version control.
> What does "svn status -v" show in that repository?
When I do that, I see the original file `foo' only once. Please note
that my bug report is erroneous. Actually, the symlink is
trunk/test/foo, pointing as trunk/src/foo. trunk/src/foo is under change
control, but the directory trunk/test and all its content is not under
change control --- I have not yet imported it. So `svn status -v' done
under trunk shows only, as far as trunk/test and its content are
concerned, this:
--8<----8<----8<----8<----8<-- begin -->8---->8---->8---->8---->8----
? test
--8<----8<----8<----8<----8<-- end -->8---->8---->8---->8---->8----
My intention was to import trunk/test to the repo with only the files
under trunk/test that aren't created by the test, so the symlinks would
in the end not be under change control, which anyway is impossible
because my SVN client does not support symlinks.
Vincent.
