Pick up changes from NetBSD:libpcap_0_9rel6
several files: date: 2006/02/27 15:53:24; author: drochner; state: Exp; avoid shadowing globals, for WARNS=2 date: 2006/02/27 15:55:30; author: drochner; state: Exp; minor constification, good for WARNS=3 now date: 2006/02/27 15:57:17; author: drochner; state: Exp; NetBSD adaption: ... -const pcap_strerror() for consistency gencode.c: date: 2006/04/26 09:24:33; author: tron; state: Exp; Add missing "const" keywords to match declarations in "pcap.h". date: 2006/10/15 19:27:21; author: christos; state: Exp; add a volatile variable to prevent vfork/longjmp clobbering. optimize.c: date: 2006/05/17 17:48:36; author: drochner; state: Exp; Make the optimizer use unsigned numbers as the kernel does. While it is not agreed on that purely unsigned arithmetics is nice, different behaviour of optimized and unoptimized code is less desirable. pcap-bpf.c: date: 2006/02/27 15:51:38; author: drochner; state: Exp; pull in from NetBSD's libpcap: use cloning bpf device on NetBSD Have the configure script check for paths.h, so that we can include it only if we have it, and use the cloning BPF device only if we're on NetBSD *and* _PATH_BPF is defined (hopefully this will keep us from using it on versions of NetBSD that don't have a cloning BPF device; if, in the future, other OSes with BPF get cloning BPF devices, we can make this work for them as well).
