Ok, now I would reject this approach because:
Suppose the three libraries where defined in different Jamfiles which of 
course are located in different directories. BJam will now compile all 
of the sources twice: all of them to build libAB, half of them to build 
libA, and the second half to build libB.

I would like to specify: compile *.cpp to *.obj instead of an "alias". 
See my post "How to build project comprising of sources in	different 
dirs" from May 6th.
