Hi,
Great, I'll test it soon!

I have a potential fix to the ninja tool so that it can decide to use response files or not. This should allow you to use your own shared response file.

 Right... thus my suggestion - well, let's call it "musing" rather than
 "suggestion" because this might not work at all:
