Five. Don't forget the #include <boost/config.hpp>

True, it isn't a lot of lines of code. But it is removing two #ifdefs, and 
that seems to me to be a worthwhile win when it comes to readability and 
understandability of code.

I'm not wedded to the additional headers, but am definitely worried about 
adding the clutter of #ifdefs to otherwise beautiful code.
