Re: svn:externals - construction of cyclic references is not prevented by TortoiseSVN

This bug is very difficult to fix. I think the only way to fix that is
keep a "track" (or queue) from root directory and check if the
external reference there is on the queue.
I agree with Lübbe. This issue is not only under windows. This issue
could be solved in svn library, when some user try to commit a new
external reference. I don't know if is possible, but this is my guess.

Rafael
