buffer overflow problems, which shouldn't be an issue since it's
not setuid.
While here, do not hardcode /usr/local, use $(PREFIX). Do not patch
the install target so that 'make install' does the man pages, add
install.man to the ${INSTALL_TARGET} variable so that both "install"
and "install.man" are done. This reduces the diff to the base source a
little, but has the same overall effect.
Among other things, it has pretty much got native FreeBSD support, does not
core dump on ^C, some sync problems, uid/gid caching fixes, symlink detection
problems, portability to new platforms..
