Not all Linux kernels that can support SocketCAN sniffing have
<linux/can/version.h>, and we don't include it directly. We *do*
include <linux/can.h>, so check for that.
Patch changed not to bother checking for the existence of <sys/socket.h>
- we already assume it exists on all platforms that support packet
capture, including Linux. I also changed the Bluetooth "not supported
on this OS" message to look like the one for CANbus, giving the host OS.

libpcap archive. A dependency has been introduced whereby the dagapi.o
object depends on functions in the dagutil.o as og DAG software release
3.4.1. This change is backwards compatible with older versions of the
DAG libraries.
Add ADDLARCHIVEOBJS, so that we can put some stuff from -ldag into the
archive library (so it's self-contained, and the configuration processes
for programs not configured with pcap-config don't have to know about
the DAG library) but not into the shared library (as we can link libpcap
with the DAG shared library, so linking with -lpcap will cause -ldag to
be linked in at run time if necessary).

Add --without-libnl configure switch
Allow build libpcap with libnl disabled even in case libnl is installed
at system.
elsewhere in the macro.
For the Alpha C compiler, don't set -std1 unless it's necessary for ANSI
mode - we don't want to limit the compiler only to C89 features and,
more importantly, C89 headers (<inttypes.h> doesn't work, on at least
some versions of Digital UNIX and some C compiler versions, with -std1).

Don't declare variables in the middle of a block; some versions of GCC
appear to warn about that.
AC_DEFINEd value with no comment, and thus eliminates the need for
acconfig.h, so get rid of it.
Get rid of AC_LBL_LIBPCAP - we don't need it, this *is* libpcap.
Get rid of AC_LBL_TYPE_SIGNAL - we don't use it.
Update comments for AC_LBL_SOCKADDR_SA_LEN and AC_LBL_CHECK_LIB to match
tcpdump's versions.
written shared library support.
Clean up some comments, and (for now) always use "$(CC) -shared" to
build shared libraries with GCC.
Merge two separate "check the platform and set the compiler options"
switches.
build "traditional" AIX shared libraries, which are archive libraries
containing shared objects, so, on AIX, we build the archive library, for
the benefit of "build libpcap and tcpdump in subdirectories of the same
directory, with tcpdump linked statically with that libpcap", but don't
install it. Newer versions of AIX, at least, also support "standard"
.so-style UN*X shared libraries, but we stick with
<Tevye>Tradition!</Tevye>.)
Fix an AIX build problem that shows up when building with GCC.
Clean up HP-UX stuff.
additional .o's to add to libpcap should go into ADDLOBJ, not V_LIBS.
Don't add -DHAVE_SEPTEL_API to V_DEFS - we add HAVE_SEPTEL_API to the
config.h file, which should be sufficient.
mac80211 devices will, regardless of whether they support the Wireless
Extensions - wmaster devices will let you turn monitor mode on but don't
appear to support the Wireless Extensions.
Support turning on monitor mode with libnl even if we don't have support
for the Wireless Extensions, just in case the Wireless Extensions go
away at some point in the future if every 802.11 device has a mac80211
driver.

with which to link applications built with a non-shared libpcap.

Add support for building shared libraries on HP-UX (not yet tested).
Attempt to set the soname (or equivalent) appropriately when building a

Use <fcntl.h> rather than <sys/file.h> in pcap-bpf.c - that's the right

Don't include <sys/timeb.h> - it doesn't define anything that pcap-bpf.c
should need.

Currently make install in libpcap never installs pcap/{vlan,bluetooth}.h
headers. Attached patch makes it install them in case support was built
in into libpcap.
Currently if there are bluetooth.h headers installed in the system
libpcap will be built with bluetooth support and it's impossible to
disable it. Attached patch adds --{en,dis}able-bluetooth switches.
Also this patch makes use of AS_HELP_STRING to let autoconf manage
output layout.

Currently SITA will be defined and sita code will be tried to build even

Don't define variables if we aren't going to use them.
If we have an unknown tpacket version (this "can't happen"), return an
