The way that the implied value is transmitted to the NOD header does
not work in the case that you have max-jobs greater than one and
you are compiling files with differing left/right sides. So I am not
keen to extend that any further.

It can't be that important, given that have survived this long without 
it. But I think we should set it. Could you let me know which byte
in the header it is or create a patch.

I don't know anything about this one. It sounds like it might be 
important though.
