Comment (by anonymous):

 in /libs/filesystem/src/operations.cpp (lines 1654-1672)


 {{{
     //  reparse point handling;
     //    since GetFileAttributesW does not resolve symlinks, try to open
 a file
     //    handle to discover if the file exists
     if (attr & FILE_ATTRIBUTE_REPARSE_POINT)
     {
       handle_wrapper h(
         create_file_handle(
             p.c_str(),
             0,  // dwDesiredAccess; attributes only
             FILE_SHARE_DELETE | FILE_SHARE_READ | FILE_SHARE_WRITE,
             0,  // lpSecurityAttributes
             OPEN_EXISTING,
             FILE_FLAG_BACKUP_SEMANTICS,
             0)); // hTemplateFile
       if (h.handle == INVALID_HANDLE_VALUE)
       {
         return process_status_failure(p, ec);
       }

       if (!is_reparse_point_a_symlink(p))
         return file_status(reparse_file, make_permissions(p, attr));
     }
 }}}

 changing
 {{{
 return file_status(reparse_file, make_permissions(p, attr));
 }}}
 to:

 return file_status('''directory_file''', make_permissions(p, attr));

 seems to fix this problem...of course i have no idea what new problems it
 might cause.
