or you can store all temporary object files. Boost.Build is the first 
build-system I work with that does not store the intermediate object 
files. I actually found updating the archive directly very neat and 
totally superior. But always recreating the _whole_ library is too 
expensive. Thus would prefer storing the intermediate files.

Another option maybe is to recreate the whole library if the Jamfile 
changes. Thus the Jamfile should set a dependency on itself.
