How does one get current libstdc++ sources?
Libstdc++ sources for all official releases can be obtained as part of the GCC sources, available from various sites and mirrors. A full list of download sites is provided on the main GCC site. Current libstdc++ sources can always be checked out of the main GCC source repository using the appropriate version control tool. At this time, that tool is Subversion. Subversion, or SVN, is one of several revision control packages. It was selected for GNU projects because it’s free (speech), free (beer), and very high quality. The Subversion home page has a better description. The “anonymous client checkout” feature of SVN is similar to anonymous FTP in that it allows anyone to retrieve the latest libstdc++ sources. For more information see SVN details.
