Make roughly buildable under FreeBSD.

The results are not perfect: the original Makefile referred to a refer
file papers/Ind, which doesn't seem to have been kept, so the
references to other publications are missing.

Initial checkin: 4.4BSD version. These files need to be updated with
current license information and adapted to the FreeBSD build
environment before they will build.
