It seems to me that the <source> feature does not work for lib targets. 
For instance, consider the following Jamfile:

lib mylib : : <source>main.cpp ;
exe myexe : : <source>main.cpp ;

Invoking 'bjam' on this file builds only the myexe target. Invoking 
'bjam mylib' just prints '...found 3 targets...', but nothing actually 
happens. Is this behavior intended or it is a bug?
