I have found the code from the suckless project, to be a great read. When I was working on a toy HTTP server I learned a lot from http://git.suckless.org/quark/ http://git.suckless.org/quark/ Another code base I enjoy reading is SBCL. When I M-. into functions and it takes me to something defined in SBCL it always is a great read, and I have learned a lot from it. FreeBSD is a great one as well, if you checkout SRC it is really illuminating to browse around the source. I have learned a lot by seeing the layout of such a large project.
