I did a little investigating. I applied the server patches to 0.15.7
(which is what they were written for) and everything works fine on
UnixWare 7. I did find that the there are at least a couple of instances
where the configuration object field is not getting initialized to
NULL. Obviously this is OK on Linux, but on UnixWare the operating system
apparently doesn't take care of this for you. I'm going to give fixing it
a shot, but I'm not totally sure what some of the configuration code is
supposed to do.
