[boost] 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
