Yes - we load WinPcap at run time; that dates back to before we bundled it with Wireshark, so we could ship a single binary that worked, without capture support, if you didn't have WinPcap installed and that worked, with capture support, if you did.  capture-wpcap.c is a bunch of wrappers that call through pointers fetched from the run-time-loaded WinPcap.

Note, BTW, that older versions of libpcap have neither pcap_compile_nopcap() nor pcap_open_dead().  I can dig up the full history (I have the impression that some versions of NetBSD have a pcap_compile_nopcap() with an extra argument, for example) at some point.
