[boost] [filesystem]: infinite-recursion with symlink

While playing around with boost::filesystem and the recursive_directory_iterator, I'm running into a infinite-recursion caused by symlinks. Not following symlinks would be, a solution, of course, but... So, is there a way to ascertain the path where the symlink is aiming at? And a second question: I didn't find anything about permission-handling - are there any plans? In my eyes, this is something essential for a filesystem-library. Thanks in advance
