I read this document quite a while ago, so fortunately, this is not an issue.
Instead, I'm _including_ sub-makefiles in a recursive way, so make has
only one common database.

Same with me, lots of generated (include) files, so gcc -MD can't track
the dependencies until the files are generted.
Anyhow, it seems very promising to look into Dave's audited objects work.
