A better version; the provided Makefile is cleaned up and made to
honor CC and CFLAGS.
New version is at
http://www.darwinsys.com/openbsd/myports/chan_unistim.tar.gz
Unistim is the proprietary protocol used by Nortel i2004 and similar
phones. chan_unistim is a revenged implementation of unistim for the
Asterisk open source PBX; as such this port depends on Asterisk.
Comments welcome on anything that needs improving before it goes in
(e.g, it doesn't yet honor CC/CFLAGS).
Tested with * running on amd64; also built on i386.
