RE: Problem with symbolic links on windows introduced on trunk somewhere between revision 22556 and 22778

Hi,

I have tested the patch that Malcolm has made and it is working. Now the symbol link file created in windows contains the internal representation of the link.

Regards,
Marc

That'll work in the sense that it won't give you an error, but it won't
populate the new contents of the new file (which should contain the
internal representation of the linke, it seems).

The problem is that svn_io_file_create() is failing because the
temporary file exists. Something like the attached should work, though
I can't test it.

Annoyingly, we don't have any symlink tests on Windows (because we can't
create symlinks there). We should fix that.

Regards,
Malcolm
