--- Comment #3 from Paolo Carlini <paolo.carlini at oracle dot com> 2012-11-27 22:04:13 UTC --- In my opinion, if you are interested in this kind of work, you should ask to have installed the required support libraries, very simple to do, just matter of a few minutes. Then, you don't need sudo to check out with svn a current tree and build it in your user directory. It's of course a very common case. If in doubt about the details just ask on gcc-help.
