Require autoconf 2.61 as a minimum, and eliminate stuff that does for you. autoconf 2.61 and later do, in AC_PROG_CC, tests to figure out how to beat non-GCC compilers into doing the closest thing to ANSI C of which they're capable, so we don't need to do them ourselves.

Clean up handling of -g and -O flags. AC_PROG_CC adds -g and -O2 to CFLAGS if you're using GCC; don't bother adding either of them, or -O, ourselves if we're using GCC. Add -O for all non-GCC compilers.

Put back AC_LBL_C_INLINE; it turns out that wasn't the cause of the inline problem, and AC_LBL_C_INLINE checks for a case that some versions of the HP C compiler don't handle, and only uses inline if that case succeeds.

AC_C___ATTRIBUTE__
Get rid of some autoconf macros not used, or no longer used, with tcpdump. Check whether __attribute__((format)) can be applied to function pointers and, if not, don't apply it to function pointers; some older versions of GCC appear to support applying it to functions, but not pointers to functions. As we've gotten rid of missing/getaddrinfo.c, don't use it.

Avoid some warnings from Sun C. Some versions of Sun C support __attribute__ but don't support the "unused" or "format" attributes - they don't fail, but they whine a lot. They also support the "noreturn" attribute, but don't allow it to be applied to function pointers, only to functions. Check whether they can be used without warnings, and use them only if they can.

NFLOG: remove header dependency, add a test case This change removes detection of linux/netfilter/nfnetlink_log.h, which was only used to provide two constants. The constants are now defined in print-nflog.c, making it possible to compile (and test) the NFLOG decoder on all systems, not only Linux. There is now a test case for the decoder, it was produced on a Linux host with: iptables -A INPUT -p udp --source 74.82.42.42 -j NFLOG --nflog-group 20 dig @74.82.42.42 ...

From: Juergen Schoenwaelder <schoenw@ibr.cs.tu-bs.de> Here is a new version of the libsmi patch for tcpdump. It provides some bug fixes and some enhancements such as access checking and better range checking. The patch also fixed a few bugs in the print_snmp.c module of tcpdump itself (unrelated to the usage of libsmi).

Add support for nommu systems. Rather than hardcode the WIN32 define, add proper fork checks to the configure script and check those. This fixes building for nommu systems which lack the fork function. While we're here though, add support for this functionality via vfork so that it does work on nommu systems. And fix an old bug where we exit properly in the forked child when the exec failed instead of just returning to the calling code (which isn't expecting it). Reviewed-By: Guy Harris <guy@alum.mit.edu>

Fix build issues with the OpenFlow printer on some systems. Don't assume we have <stdint.h>. Instead, use the AC_TYPE_ macros to ensure we have the C99 intN_t and uintN_t types; we already include <inttypes.h> in tcpdump-stdinc.h iff we have it. Get rid of the structure declarations in openflow-1.0.h, as they have zero-length arrays (not supported by all the compilers people might be using) and as 1) they're only used in sizeof() and 2) after each one there's an assertion to check that sizeof() returns a specific numerical value so, instead, just #define various _LEN items to those numerical values and use them. Add an openflow.h header with a #define for the length of the basic header, and move the declaration of of10_header_body_print() there.

We still need u_intN_t. Some libpcap headers use them, and even if we change libpcap to use uintN_t, we don't require that tcpdump 4.x go with libpcap 1.x - we allow people to install the latest tcpdump even if they have an older libpcap and don't want to install a newer one. However, we now define them in terms of the C99 uintN_t types, rather than trying to guess what's appropriate; using unsigned long long for u_int64_t meant that, on some platforms, u_int64_t didn't match PRI[doux]64, and using unsigned long obviously won't work on ILP32 platforms. Also, we already had calls to the autoconf macros for C99 types; get rid of the ones we added. Also also, clean up a comment in tcpdump-stdinc.h.

Properly define {u_}intN_t types when testing pcap/*.h headers. pcap/bluetooth.h and pcap/usb.h require those types, so we check for those types before checking those headers, and we include "tcpdump-stdinc.h" in the tests, so the appropriate headers to define those types get pulled in.

Simplify the detection of OpenSSL libcrypto by using standard autoconf macros rather than a local copy of AC_LBL_SSLEAY. AC_LBL_SSLEAY is old and has not kept pace with some more recent developments in packaging like Debian and Ubuntu's multiarch support. The autoconf macros have been updated to handle multiarch so using them means that tcpdump gains the ability to be built with libcrypto on these new multiarch distros and to work successfully with Travis CI, which uses Ubuntu 12, which is one such multiarch distro (see GH-32). Fixes GH-33

Expand srcdir in V_INCLS at configure time, not make time. That way, if we temporarily set CPPFLAGS to include V_INCLS, it'll work correctly.

Have the configure script arrange that the Makefile define _U_ appropriately, and that GNUmakefile and the MSVC++ project file define it apppriately, as we do with libpcap, rather than defining it in "interface.h". Undo the rcsid-shuffling and addition of extra #includes, as we no longer need to arrange that "interface.h" be included before using _U_ in an RCS ID or copyright.
