whether it succeeds or fails, so you can't erase a "no" result and try
again with a different header. Use AC_CHECK_DECL, which doesn't define
HAVE_DECL_xxx, and then explicitly define it based on whether we found a
declaration or not.
don't have __attribute__ support in the compiler.
While we're at it, get rid of the declaration of bpf_error() in
gencode.c, as it's already declared in gencode.h.
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>.

from the main branch.
on HP-UX, just keep trying different SAPs until we find one that doesn't
return EBUSY, as attempting to use a SAP that some other descriptor is
already bound to returns EBUSY.
What it does includes checking whether the packet is of the type
specified by the <proto> argument, so there's no need to add such a
check when checking whether the ISO protocol type field has a particular
value; remove the extra check against the ISO protocol.

by checking the proto against the ethermtu and bumping
the link-layer offset by two.
-add support for vlan and mpls hierarchies by not absolute
setting offsets but rather incrementing them;

=filters for mpls label 17 encapsulated in vlan 300
<netinet/ether.h> declares ether_hostton(), so the failure to find it
declared in <netinet/in_ether.h> doesn't cause us to assume we won't
find it anywhere.

Get rid of the # in the "Rechecking with some additional #includes"
message, as it's a shell comment character and screws up the script.

includes and definitions).
Log a message before doing the second test, to show why we're testing
twice.
on Solaris, it's a "gethostbyname() -ish function", and we'll find it
only when we're linking with whatever libraries are required for finding
those functions.
Get the AC_LBL_LIBRARY_NET macro from tcpdump; that macro works with
autoconf 2.5x, but the one here didn't.
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).
one packet from the kernel at a time, when the filter is changed, clear
the libpcap buffer to discard packets read from the kernel before the
filter was changed.
