"To" should not be listed in the commit message and "Cc" means that you
really do expect Stephen and myself to say something - i.e. it's not the
same as To and Cc in the email header.

Don't you need these constants in the COMPILE_TEST case?

Please space this out over 3 lines with proper indentation.

I don't think we want to duplicate all the defines, so please prepend a
separate patch grouping them at the top.
