In general, an empty config.hpp means C++0x. That did seem to be the
consensus decision, and I think everyone went into it understanding
the consequences. It looks like the decision was made here (only the
first few replies are relevant):

http://thread.gmane.org/gmane.comp.lib.boost.devel/175638

I also found some earlier discussion where I think the change was
first proposed (only the first subthread):

http://thread.gmane.org/gmane.comp.lib.boost.devel/151193

Interestingly, someone proposed that the C++0x BOOST_NO_ macros should
be defined by default, and then undefined in the config headers.

Personally, I don't have a strong opinion and will follow the consensus.
