Yes, in two ways
1. Currently, all my unit tests just link to the libraries where the testsed 
unit is placed.
2. V2 has an "obj" rule. It can be used to compile a file only once, it that's 
really needed:

exe first : first.cpp shared ; 
exe second : second.cpp shared ;
obj shared : shared.cpp ;

Not the most short way, but viable.
