a) a freebsd client that compiles, and to a certain extent, works. Should
not be used except by people doing freebsd client development
b) configure glue for freebsd 4.3, 4.4, and 4.5
c) freebsd tfileserver support. Note that, by default, this isn't very
interesting, as the supported freebsd pthreads are just as cooperative as
LWP. if you install the linuxthreads port and swap the MT_* variables in
osconf.m4, you will get a more traditional tfileserver though. configure
glue for that will be forthcoming at some point.
d) a maybe-fix that sets sin_len in sockaddrs on platforms that have them.

(and also a fix for the AC_PROG_CC issue which affects autoconf 2.13 and 2.5x
 on same conf files issue)
