This has been solved long ago. Check the awesome advanced dependency
generation article by Paul.



The issue you raise (as well as others) is discussed, hopefully
clearly, in this article [*].


Thanks for sharing that great article!

I'll definitely have to have a look at many or all of the articles in that website!

I've already applied some of the improvements there, reducing no-op make times to 0.7 s in single-process and 0.35 with 'make -j'. I'll keep adding the other improvements too.
