multiple definition problem on linking

Subject: multiple definition problem on linking

I'm not sure what I did to cause the following, since the multiple
definition error does not appear to be on a symbol that I defined myself
anywhere.  It's fine if I just compile and link DBSubscriberRec, but as soon
as I try to link DBSubscriber with it, I get this link error.   Also, this
builds fine on Solaris with a different compiler.  This build attempt is on
a Sun running Red Hat Linux 6.2.
