[boost] old filesystem improvements

Greetings, In the past, I've posted various patches to the filesystem library. Some of them were implemented, and some were not. In particular, I offered patches to implement symlink and readlink http://lists.boost.org/MailArchives/boost/msg52521.php the who() function for filesystem exceptions, http://lists.boost.org/MailArchives/boost/msg52522.php copy and copy_directory, http://lists.boost.org/MailArchives/boost/msg58652.php and hard links. http://lists.boost.org/MailArchives/boost/msg61975.php Since these posts, I've modified and extended some of them a little. I'm happy to post the new versions, but I am wondering if there is actually any interest in any of these things. Regards, Walter Landry wlandry@ucsd.edu
