Sure, I'll wait until you say it's a good time. It does remove a
dozen or so hunks of difference, which should hopefully make that job
easier eventually but I don't want to get in your way. I can see
there are a few more trivialities we could synchronise on, like const
keywords, to kill useless diffs (either dropping local improvements or
sending patches upstream).

Yeah. My first swing at this touched only .c files, no .h files, with
that in mind.
