There is an exception to the path mangling for //unc/paths, if that's
what you mean.

>From [1]:

  if (path[0] == '/' && path[1] == '/')
    {
      int tidx = 2;
      while (spath[tidx] && spath[tidx] == '/')
	  tidx++;
      if (strchr (&spath[tidx], '/'))
	{
	  retpathcpy (spath);
	}
      else
	{
	  retpathcpy (&spath[1]);
	}
      return ScrubRetpath (retpath);
    }

I haven't tested, since I don't have easy access to a Windows test
setup.
