* nametoaddr.c with DECNETLIB defined needs <netdnet/dnetdb.h>
included. And which again needs <sys/types.h>.
* Remove "IP6_misc.h" since it's already included in pcap-stdinc.h
(ref. my patch to pcap-stdinc.h).

Add missing "const" keywords to match declarations in "pcap.h".

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.

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).
source directory and the target include directory, and have include
files at the top-level directory to include those headers, for backwards
compatibility.
Update the FILES and INSTALL.txt files to reflect current reality.
routines, including malloc() and company - and for string routines used
in this file, which aren't necessarily declared in <memory.h>, so
include <string.h>.
and if including it declares ether_hostton(), and define
HAVE_DECL_ETHER_HOSTTON appropriately, and use that to determine whether
to define it ourselves, rather than having a set of OSes that don't need
it, as that set can change over time.
Make the default declaration of "ether_hostton()" declare its first
argument as "const char *", as that's what it's *supposed* to be
(although it's not declared as such in some OSes, so we still have to
cast a "const char *" when passed as the first argument).
each source file, only the headers that file needs, and all the headers
it needs in order to compile on various platforms and not to get any
avoidable compiler warnings on those platforms (as well as any
incomplete structure definitions needed to avoid those warnings).
That also means that <pcap.h> doesn't include <pcap-stdinc.h> on UNIX;
we don't want it to include <pcap-stdinc.h>, at least on UNIX, as doing
so
1) would mean we'd have to install that, so that programs can
build with libpcap
and
2) would mean that programs including <pcap.h> would drag in a
bunch of header files that they don't need.
Put a newline at the end of "inet.c" - the Sun C compiler doesn't like
it if the last line doesn't end with a newline.
"struct rtentry" (in <net/if.h> on some systems, e.g. Digital UNIX 4.0,
there are prototypes for kernel functions that include "struct mbuf *"
and "struct rtentry *" arguments, and they are included even if you're
just user-mode code).
We don't need to include <netinet/if_ether.h> unless we have
"ether_hostton()", and we don't need to include <net/if.h> unless we're
including <netinet/if_ether.h>, and we don't need to define "struct
mbuf" or "struct rtentry" unless we're including <net/if.h>.
"patches@tcpdump.org" by Jonathan Wilkins
<jwilkins@madscience.dyndns.org>, we don't declare "ether_hostton()" on
FreeBSD - it's declared in <net/ethernet.h> in 3.0 and later, and is
declared with the first argument as "const char *" in 4.0 and later so
that if we declare it with the first argument as "char *" we get errors.
(If we declare it with "const char *", you get errors on FreeBSD 3.x and
other systems that *don't* declare it with "const char *".)
XXX - should it go, instead, into "lbl/os-XXX.h" files, for those OS
versions that don't declare it, and not be declared at all here?
