Yes , clearly that would be the ideal but I don't have the time to get 
in that deep and I would not want to deprive anyone getting paid by 
atmel of their livelihood ;)

Thanks for the pointers, Yann.

There's quite a bit going on but it does not look that complicated on 
the bottom line (if I short circuit some of the ct-ng options and ignore 
additions to err_log).

 From those functions you note and looking at the dir structures , it 
seems like this should be enough.

==================================
attempt fake state-save for manual binutils
==================================

cd targets/avr32-unknown-none/state
mkdir binutils
cp gmp/* binutils
# ignore adding to log file
cd ../../..
ct-ng build RESTART=binutils+


I have not bitten the bullet on that yet since I don't want to blast 
what I've achieved so far. Would that be enough as a quick hack or am I 
missing something significant?

Thanks again, Peter.
