Sorry... I've been rather busy since you asked this.. And I wont be able 
to really respond to the rest of the email in this thread. But, since 
you are doing assembly, why don't you also use the ".no_dead_strip 
<symbol>" Mac assembler directive?

Note, I recently add a <force-load>library.a feature to darwin.jam which 
might also be of use.
