[Song, Ruiling]

It is better you add one or two lines of commit message to describe what kind of warnings are fixed in you patch.

For such kind of fix, it's better you simply remove the old code. Don't leave it here with comment.
For the comment line "In C++0x std::auto_ptr will be deprecated in favor of std::unique_ptr", you can place it in commit message.

Why do we need this weird delete()??

I noticed you remove the "inline", is it because the function too big for ICC?
