I encountered the same problem trying to compile the latest libpcap-1.1 sources
on a RHEL5 system.  I fixed it with the following patch to fad-getad.c:

--- libpcap-1.1/fad-getad.c     2010-03-11 20:56:53.000000000 -0500
+++ libpcap-1.1-mine/fad-getad.c        2010-03-31 16:05:56.000000000 -0400

 # endif
 #endif
