before writing my own wrappers I would like to see if the overhead of 
tracking chars is acceptable for me. I tried putting the following into 
my cpp but it won't compile:

#include <boost/serialization/tracking.hpp>
BOOST_CLASS_TRACKING(char, boost::serialization::track_selectivly)

I guess I need to change the default "implementation_level" for char. 
What other things do I need to change so as to make a fundamental type 
trackable?

Thanks,
