Well, I am trying to understand what's going on here and how things are
supposed to work. I run make build, and after rb.h was renamed to rbtree.h
I get warnings about rb.h not found in /usr/src/lib/librump. Each time
I type make dependall in that directory, the dependencies are not being
re-made, I get the same warnings and the files that used to depend in
rb.h get rebuilt. How does your patch address this?

I understand, but I want to find a solution that does not cause make to
look for things in unexpected places.
