you can certainly first compile manually just your new files alone if you 
want (look at the ocamlc commands that are issued when you 'make nab' and do 
stg similar for your files )

but i'm not sure i understand the question.. what 
difference does it make whether or not you compile the whole of NAB? ocaml 
compilation is very fast (on any reasonable hw) anyway.

not missing anything that i can see for a first-pass implementation.
