Hello, I have just created a new branch for development of C++0x-specific features in the GNU C++ front end. The branch is branches/cxx0x-branch in Subversion, and information about this branch is available at http://gcc.gnu.org/projects/cxx0x.html.
The intent of this branch is to collect all of the C++0x features into a single place, so that users of this branch can get a better feel for the C++0x language and we can work on handling interactions among C++0x features. Most implementations of C++0x features should still go into mainline, when possible, but on the branch we have a little more freedom to commit partially-implemented features. Jason Merrill and I will maintain this branch. As features on this branch mature, we hope to merge them into the mainline compiler under the "experimental" C++0x mode. Cheers, Doug
