Until the release bits the following was true:

    Until such time as Rick Jones can figure-out or be told how to make it
    automagic in the configure script, prior to configure on solaris, you
    may need:

    CFLAGS="-lsocket -lnsl -lkstat"

    and if you are trying to compile the SCTP tests:

    CFLAGS="-lxnet -lsocket -lnsl -lkstat -D_XOPEN_SOURCE=500 -D__EXTENSIONS__"

as the release bits have a "smarter" configure script, and the SCTP
tests use libsctp, the above no longer applies.  It should all just be
automagic (although for SCTP you still must --enable-sctp at configure
time)

Beware CPU util figures on anything before Solaris 10 that does not
say 100%, and still be a triffle cautious with Solaris 10 CPU util
reports.  The CPU time accounting mechanisms either do not track time
spent servicing interrupts, or do so in parallel with time spent in
user/kernel/idle which means that some idle time isn't _really_ idle
time.

And beyond that, it is still not clear if the CPU utilization reported
on systems with hardware threading support (eg UltraSPARC-T1) is
really accurate even ignoring the issue with interrupt time.  It is
likely that to be truely accurate, it is necessary to know how much
"real work" any one strand performed.
