[sorry for the duplicate, replying all this time]

Is this necessary for the entire patch, or just the parts that touch 
existing parts of the toolchain.  For example, do you want me to run 
this on libitm/, etc?  I'm really trying to minimize changes (even 
whitespace stuff) at the last minute, but if you think it's imperative, 
I will do so.
