Probably an oversight.  The .def files weren't updated when the  
libpcap base of WinPcap was updated to a version that includes  
pcap_fopen_offline(); the release notes for libpcap release that first  
included them might not have mentioned that routine.

(So what exactly *are* the benefits of requiring a .def file when you  
build a dynamically-linked library?  No UN*X that I know of requires  
that the exported functions be explicitly declared when you build a  
dynamically-linked shared library....)
