Do you think the following plan make ssense?
- I assume that a build from git clean -xdf shows all the steps that
must happen with 100% certainty.
- I'd then make bootstrap + look for a difference.
- Then same procedure for simple make in the toplevel dir,
- after there is only a C file changed
- after only a Lisp file is changed
Sounds good.
You might also want to compare the timestamp of `loaddefs.elc` compared to
the timestamp of `emacs.pdmp` in your build directory (assuming you
still have it around).
