That page is supposed to provide instructions on bugs and bug reporting, and I don't think we've got all that many users still interesting in those versions, do we? (And it makes this documentation more concise.) If you agree, I'll be happy to make this change. Just let me know. Gerald

I've committed the changes to htdocs/projects/cxx0x.html now, but not the htdocs/bugs/index.html change. I agree that the 3.x info is not useful on that page. Maybe we should just drop the whole "Common problems when upgrading the compiler" section, because info on 3.x is outdated, nearly everybody understands that C++ compilers conform to the standard these days (even MS got in on that act eventually ;-) and the info about breaking the C++ ABI with every major release is just wrong!
