That's very close to what I want to achieve. But I'll go with the perl option since my initialization 
code is much bigger. It's, in fact, bigger than the main code. It would be very error prone for me
to express everything as offsets from __BSS_RUN__. But for normal initialization tasks I think
your trick is way more clever :)
