that this source is compiled against. This source is referenced by install which is needed as a build tool and must be able to compile against NetBSD headers and libraries if we have a hope of supporting another architecture. With this change, that's two working programs down and 3945 (?) to go. The other one was make, but that didn't need any changes to work under FreeBSD/Alpha. 8-)
