[Boost-build] iterator/transform_iterator.hpp has more dependencies than it needs?

My work likes to keep a minimal subset of boost in the project tree.  One of 
the libraries we are using (I can't remember which off hand) requires 
transform_iterator.hpp which includes boost/function.hpp.  I noticed when 
merging in the latest RC updates that I had commented out this header as it 
doesn't appear to be necessary and saves me from bringing yet another 
library into the mini-boost folder.

Is this dependency actually necessary?

Thanks,

Michael Marcin
