 176         with libpcap.
 177       Avoid casting hack for the Windows cleanup-on-exit routine.
 178       Use %zu format for one case of printing a size_t.

 188       Optimizer fix from Archit Shah to recompute dominators after
 189         moving code (#976); fixes #945 (although the resulting filter
 190         isn't empty).
 191       Optimizer fix from Archit Shah to mark value as unknown when store
 192         of that value is deleted (#972); fixes #143, #434, #436, #437,
 193         and #1076.

 213       Fix AF_LINK handling on illumos.
 214     macOS:
 215       Redid the availability macros to be closer to what Apple's doing
 216         in recent SDKs, including tagging pcap-namedb.h routines.

 234       Work around a bug in Npcap 1.00 in case of driver version mismatch.
 235       Don't call WSACleanup() when handling a failed WSAStartup().
 236     BSD, macOS, AIX, Solaris 11, Linux:
 237       Add a new error PCAP_ERROR_CAPTURE_NOTSUP, for use if a capture
 238         mechanism is not present, in the hopes that, for example,
 239         attempts to capture on Windows Services for Linux 1, in which
 240         the NT kernel attempts to simulate Linux system calls but does
 241         not support packet sockets, can get an error that better
 242         indicates the underlying problem.

 251         double frees in some cases.
 252       Don't define SOCKET ourselves; instead, define PCAP_SOCKET as int
 253         on UN*Xes and as SOCKET on Windows.
 254       CVE-2024-8006: Fix pcap_findalldevs_ex() not to crash if passed a
 255         file:// URL with a path to a directory that cannot be opened.
 256     Savefiles:
 257       Handle DLT_/LINKTYPE_ mapping better, to handle some
 258         OpenBSD-specific link types better.
 259       Treat if_tsoffset as signed in pcapng files, as the spec says.
 260       Don't try to fix the "real" length for isochronous USB
 261         transfers if the number of USB descriptors is too large.
 262       Reject pcap files where one of the reserved fields in the
 263         "link-layer type plus other stuff" is non-zero.
 264     Building and testing:
 265       Add a configure option to help debugging (--enable-instrument-functions).
 266       Improved tests and error reporting for uses of pkg-config, and
 267         improve help message.
 268       Fix Haiku build.
 269       With CMake, install headers in CMAKE_INSTALL_INCLUDEDIR rather
 270         than just include.
 271       Build libpcap.a before building test programs.
 272       Print address family numerically, as well as symbolically,
 273         in findalldevstest.
 274       Fail with suggestions, rather than failing over to no capture
 275         support, if no capture mechanism was found.  Fixes issue #1016.
 276       Don't indent comments in Make, as that may cause them not to be
 277         recognized as comments.
 278       Don't check for libssl if we aren't going to use it.
 279       Better handle enabling and disabling of sanitizers.  Fixes issue
 280         #1171.

 292         '-Wunused-but-set-parameter', and '-Wunused-but-set-variable' in
 293         devel mode if supported.
 294       Don't ignore spaces between CMAKE_C_FLAGS and DPDK_C_FLAGS with
 295         CMake.
 296       Use noreturn and __format__ with XL C 7.0 and later.
 297       Check for the same -W flags in autotools and CMake.

 354 Saturday, December 31, 2022 / The Tcpdump Group
 355   Summary for 1.10.2 libpcap release
 356     Source code:
 357       Use __builtin_unreachable() in PCAP_UNREACHABLE.
 358       Use AS_HELP_STRING macro instead of AC_HELP_STRING in the
 359         configure scripts, to avoid deprecation warnings.
 360       Change availability tags in pcap.h to make it easier to
 361         arrange for it to be used in Darwin releases.
 362       Use AS_HELP_STRING for --enable-remote.
 363       Fix some formatting string issues found by cppcheck.
 364       Various small code and comment cleanups.
 365       Use PCAP_ERROR (defined as -1) rather than explicit -1 for
 366         functions the documentation says return PCAP_ERROR.
 367       Remove unused code from the filter compiler.
 368       Use _declspec(deprecated(msg)) rather than __pragma(deprecated)
 369         for Windows deprecation warnings, so the message that was
 370         specified shows up.
 371       diag-control.h: define PCAP_DO_PRAGMA() iff we're going to use it.
 372       Use "%d" to print some signed ints.
 373       Use the Wayback Machine for a removed document in a comment.
 374       Add some const qualifiers.
 375       RDMA: Use PRIu64 to print a uint64_t.
 376     "Dead" pcap_ts from pcap_open_dead() and ..._with_tstamp_precision():
 377         Don't crash if pcap_breakloop() is called.
 378     Savefiles:
 379       Fix pcap_dispatch() to return number of packets processed, rather
 380         than 0, even at EOF.
 381       If we get an error writing the packet header, don't write the
 382         packet data.
 383       Put PFLOG UID and PID values in the header into host byte order
 384         when reading a LINKTYPE_PFLOG file.
 385       Put CAN ID field in CAN pseudo-headers for LINUX_SLL2, as we do
 386         for LINUX_SLL.
 387       Fix incorrectly-computed "real" length for isochronous USB
 388         transfers when reading savefiles.
 389       Don't crash if pcap_can_set_rfmon() is called.
 390       Fix pcap_offline_read() loop.
 391     Capture:
 392       Never process more than INT_MAX packets in a pcap_dispatch() call,
 393         to avoid integer overflow (issue #1087).
 394       Improve error messages for "no such device" and "permission
 395         denied" errors.
 396       SITA: Fix a typo in a variable name.
 397     Packet filtering:
 398       Get PFLOG header length from the length value in the header.
 399       Support all the direction, reason, and action types supported by
 400         all systems that support PFLOG.
 401       Don't require PFLOG support on the target machine in order to
 402         support PFLOG filtering (also fixes issue #1076).
 403       Expand abbreviations into "proto X" properly.
 404       gencode.c: Update a comment about the VLAN TPID test.
 405       Add the minimum and maximum matching DLTs to an error message.
 406     Linux:
 407       Fix memory leak in capture device open (pull request #1038).
 408       Fix detection of CAN/CAN FD packets in direction check (issue
 409         #1051).
 410       Fix double-free crashes on errors such as running on a kernel with
 411         CONFIG_PACKET_MMAP not configured (issue #1054).
 412       Use DLT_CAN_SOCKETCAN for CANbus interfaces (issue #1052; includes
 413         changes from pull request #1035).
 414       Make sure the CANFD_FDF can be relied on to indicate whether a
 415         CANbus packet is a CAN frame or a CAN FD frame
 416       Improve error message for "out of memory" errors for kernel
 417         filters (see issue #1089).
 418       Fix pcap_findalldevs() to find usbmon devices.
 419       Fix handling of VLAN tagged packets if the link-layer type is
 420         changed from DLT_LINUX_SLL to DLT_LINUX_SLL2 (see issue #1105).
 421       Always turn on PACKET_AUXDATA (see issue #1105).
 422       We require 2.6.27 or later, so PACKET_RESERVE is available.
 423       Make sure there's reserved space for a DLT_LINUX_SLL2 header
 424         when capturing.
 425       Correctly compute the "real" length for isochronous USB transfers.
 426       Don't have an eventfd descriptor open in non-blocking mode, so as
 427         not to waste descriptors.
 428       netfilter: Squelch a narrowing warning (To be look at before 2038).
 429     BPF capture (*BSD, macOS, AIX, Solaris 11):
 430       Fix case where a device open might fail, rather than falling back
 431         to a smaller buffer size, when the initial buffer size is too
 432         big.
 433       Use an unsigned device number to iterate over BPF devices, to
 434         squelch a compiler warning.
 435     NetBSD:
 436       Fix handling of LINKTYPE_HDLC/DLT_HDLC.
 437     rpcap:
 438       Fix unaligned accesses in rpcapd (pull request #1037).
 439       Fix code to process port number.
 440       Clean up findalldevs code in rpcapd.
 441       Clean up bufferizing code.
 442       Fix a file descriptor/handle leak in pcap_findalldevs_ex()
 443         (Coverity CID 1507240).
 444       Improve error messages for host and port resolution errors.
 445       Fix connect code not to fail if both IPv4 and IPv6 addresses are
 446         tried.
 447       Improve connect failure error message.
 448       Provide an error message for a bad authentication reply size.
 449       For link-layer types with host-endian fields in the header, fix
 450         those fields if capturing from a server with a different byte
 451         order.
 452       Suppress temporarily the warnings with "enable remote packet capture".
 453     Windows:
 454       Add support for NdisMediumIP (pull request #1027).
 455       Don't require applications using pcap to be built with VS 2015 or
 456         later.
 457       Use the correct string for the DLL VersionInfo.
 458       Remove unnecessary DllMain() function.
 459       Correctly handle ERROR_INVALID_FUNCTION from
 460         PacketGetTimestampModes() (indicate that WinPcap or an older
 461         version of Npcap is probably installed).
 462       Fix use-after-free in some cases when a pcap_t is closed.
 463       Make sure an error is returned by pcap_create_interface() if
 464         PacketOpenAdapter() fails.
 465       Return an error if the driver reports 0 timestamp modes supported.
 466       Close the ADAPTER handle for some errors in
 467         pcap_create_interface().
 468       Get rid of old unmaintained VS project files.
 469       Fix deprecation warning for pcap_handle().
 470       Npcap is now at npcap.com, not npcap.org.
 471       Make sure "no such device" and "no permission to open device"
 472         errors show up in pcap_activate(), not pcap_create() (fixes,
 473         among other things, tcpdump -i <interface-number>).
 474       npcap: squelch deprecation warnings for kernel dump mode.
 475     Haiku:
 476       Implement pcap_lib_version(), as now required.
 477       Handle negative or too-large snaplen values.
 478       Fix various build issues and warnings.
 479     Building and testing:
 480       Update configure-time universal build checks for macOS.
 481       Update config.guess and config.sub.
 482       If we look for an SSL library with pkg-config in configure script,
 483         try pkg-config first.
 484       If we have pkg-config and Homebrew, try to set pkg-config up to
 485         find Homebrew packages.
 486       Handle some Autoconf/make errors better.
 487       Use "git archive" for the "make releasetar" process.
 488       Remove the release candidate rcX targets.
 489       Fix compiling on Solaris 9/SPARC and 11/AMD64.
 490       Address assorted compiler warnings.
 491       Fix cross-building on Linux for Windows with mingw32 for Win64
 492         (pull request #1031).
 493       Properly set installation directory on Windows when not compiling
 494         with MSVC.
 495       Fix configure script checks for compiler flags.
 496       Give more details if check for usable (F)Lex fails.
 497       Fix compiling with GCC 4.6.4.
 498       Don't use add_compile_options() with CMake, as we currently don't
 499         require 2.8.12, where it first appeared.
 500       Don't provide -L/usr/lib for pkg-config --libs in pkg-config.
 501       Fix error message for inadequate Bison/Berkeley YACC.
 502       configure: correctly do some DPDK checks.
 503       Only use pkg-config when checking for DPDK.
 504       Allow the path in which DPDK is installed to be specified.
 505       Use pkg-config first when checking for libibverbs.
 506       CMake: fix check for libibverbs with Sun's C compiler.
 507       Have CMake warn if no capture mechanism can be found.
 508       Don't do stuff requiring 3.19 or later on earlier CMakes.
 509       Squelch some CMake warnings.
 510       Fix diag-control.h to handle compiling with clang-cl (issues
 511         #1101 and #1115).
 512       Cleanup various leftover cruft in the configure script.
 513       Fix building without protochain support. (GH #852)
 514       Check for a usable YACC (or Bison) and {F}lex in CMake, as we do
 515         in autotools.
 516       Only check for a C++ compiler on Haiku, as that's the only
 517         platform with C++ code, and make sure they generate code for
 518         the same instruction set bit-width (both 32-bit or both 64-bit)
 519         (issue #1112).
 520       On Solaris, check the target bit-width and set PKG_CONFIG_PATH
 521         appropriately, to handle the mess that is the D-Bus library
 522         package (issue #1112).
 523       Fix generation of pcap-config and libpcap.pc files (issue #1062).
 524       pcap-config: don't assume the system library directory is /usr/lib.
 525       pcap-config: add a --static-pcap-only flag.
 526       Cirrus CI: Use the same configuration as for the main branch.

 531       Cirrus CI: Add the libssl-dev package in the Linux task.
 532       Cirrus CI: Add the openssl@3 brew package in the macOS task.
 533       Get "make shellcheck" to pass again.
 534       CMake: Build valgrindtest only if Autoconf would.
 535       CMake: use ${CMAKE_INSTALL_SBINDIR} rather than just sbin.
 536       CMake: use NUL: as the null device on Windows.
 537       autoconf: fix typo in test of macOS version.
 538       Makefile.in: Add two missing files in EXTRA_DIST.
 539       autotools, cmake: provide an rpath option if necessary.
 540       configure: get rid of the attempt to auto-run PKG_PROG_PKG_CONFIG.

 551         the web site.
 552       Clean up man pages.
 553       Move README.capture-module to the web site.
 554       Improve some protocol details in pcap-filter(7).
 555       Refine "relop" notes in pcap-filter(7).
 556       In pcap-filter(7) "domain" is an id.
 557       Discuss backward compatibility in pcap-filter(7).
 558       Other improvements to pcap-filter(7).
 559       Document pcap_breakloop(3PCAP) interaction with threads better.
 560       Document PCAP_ERROR_NOT_ACTIVATED for more routines.
 561
 562 Wednesday, June 9, 2021:
 563   Summary for 1.10.1 libpcap release:
 564     Packet filtering:
 565       Fix "type XXX subtype YYY" giving a parse error
 566     Source code:
 567       Add PCAP_AVAILABLE_1_11.
 568     Building and testing:
 569       Rename struct bpf_aux_data to avoid NetBSD compile errors
 570       Squelch some compiler warnings
 571       Squelch some Bison warnings
 572       Fix cross-builds with older kernels lacking BPF_MOD and BPF_XOR
 573       Fix Bison detection for minor version 0.
 574       Fix parallel build with FreeBSD make.
 575       Get DLT_MATCHING_MAX right in gencode.c on NetBSD.
 576       Define timeradd() and timersub() if necessary.
 577       Fix Cygwin/MSYS target directories.
 578       Fix symlinking with DESTDIR.
 579       Fix generation of libpcap.pc with CMake when not building a shared
 580           library.
 581       Check for Arm64 as well as x86-64 when looking for packet.lib on
 582           Windows.
 583     Documentation:
 584       Refine Markdown in README.md.
 585       Improve the description of portrange in filters.
 586       README.linux.md isn't Markdown, rename it just README.linux.
 587     pcapng:
 588       Support reading version 1.2, which some writers produce, and which
 589           is the same as 1.0 (some new block types were added, but
 590           that's not sufficient reason to bump the minor version number,
 591           as code that understands those new block types can handle them
 592           in a 1.0 file)
 593     Linux:
 594       Drop support for text-mode USB captures, as we require a 2.6.27
 595           or later kernel (credit to Chaoyuan Peng for noting the
 596           sscanf vulnerabilities in the text-mode code that got me to
 597           realize that we didn't need this code any more)
 598       Bluetooth: fix non-blocking mode.
 599       Don't assume that all compilers used to build for Linux support
 600           the __atomic builtins
 601     Windows:
 602       Add more information in "interface disappeared" error messages, in
 603         the hopes of trying to figure out the cause.
 604       Treat ERROR_DEVICE_REMOVED as "device was removed".
 605       Indicate in the error message which "device was removed" error
 606           occurred.
 607       Report the Windows error status if PacketSendPacket() fails.
 608       Use %lu for ULONGs in error message formats.
 609       Don't treat the inability to find airpcap.dll as an error.
 610       Ignore spurious error reports by Microsoft Surface mobile
 611           telephony modem driver
 612     rpcap:
 613       Clean up error checking and error messages for server address
 614           lookup.
 615

 619     Label most APIs by the first release in which they're available
 620     Fix some memory leaks, including in pcap_compile()
 621     Add pcap_datalink_val_to_description_or_dlt()
 622     Handle the pcap private data in a fashion that makes fewer
 623        assumptions about memory layouts (might fix GitHub issue #940
 624        on ARM)
 625     Fix some thread safety issues
 626     pcap_findalldevs(): don't sort interfaces by unit number
 627     Always return a list of supported time-stamp types, even if only
 628         host time stamps are supported
 629     Increase the maximum snaplen for LINKTYPE_USBPCAP/DLT_USBPCAP
 630     Report the DLT description in error messages
 631     Add pcap_init() for first-time initialization and global option
 632         setting; it's not required, but may be used
 633     Remove (unused) SITA support
 634     Capture file reading:
 635         Correctly handle pcapng captures with more than one IDB with a
 636             snapshot length greater than the supported maximum
 637     Capture file writing:
 638         Create the file in pcap_dump_open_append() if it doesn't exist
 639     Packet filtering:
 640         Fix "unknown ether proto 'aarp'"
 641         Add a new filter "ifindex" for DLT_LINUX_SLL2 files on all
 642             platforms and live Linux captures
 643         Add a hack to the optimizer to try to catch certain optimizer
 644             loops (should prevent GitHub issue #112)
 645         Show special Linux BPF offsets symbolically in bpf_image() and
 646             bpf_dump()
 647         Added support for ICMPv6 types 1-4 as tokens with names
 648         Remove undocumented and rather old "ether proto" protocols
 649         Catch invalid IPv4 addresses in filters
 650         Don't assume ARM supports unaligned accesses
 651     Security and other issues found by analysis:
 652         Fix various security issues reported by Charles Smith at Tangible
 653             Security
 654         Fix various security issues reported by Include Security
 655         Fix some issues found by cppcheck.
 656         Add some overflow checks in the optimizer
 657     rpcap:
 658         Support rpcap-over-TLS
 659         Redo protocol version negotiation to avoid problems with old
 660             servers (it still works with servers using the old negotiation,
 661             as well as servers not supporting negotiation)
 662         Error handling cleanups
 663         Add some new authentication libpcap error codes for specific
 664             errors
 665         Fix some inetd issues in rpcapd
 666         Fix rpcapd core dumps with invalid configuration file
 667         On UN*X, don't have rpcapd tell the client why authentication
 668             failed, so a brute-force attacker can't distinguish between
 669             "unknown user name" and "known user name, wrong password"
 670         Allow rpcapd to rebind more rapidly (GitHub issue #765)

 679             deprecated
 680         Fix compilation of pcap-tc.c
 681     Linux:

 683         Handle systems without AF_INET or AF_UNIX socket support
 684         Get rid of Wireless Extensions for turning monitor mode on
 685         Proper memory sync for PACKET_MMAP (may prevent GitHub issue
 686             #898)
 687         Drop support for libnl 1 and 2.
 688         Return error on interface going away, but not if it just went
 689             down but is still present
 690         Set socket protocol only after packet ring configured,
 691             reducing bogus packet drop reports
 692         Get ifdrop stats from sysfs.

1154         Don't crash if "wlan addr{1,2,3,4}" are used without 802.11
1155           headers
1156         Do filtering on USB and Bluetooth capturing
1157         On FreeBSD/SPARC64, use -fPIC - it's apparently necessary
1158         Check for valid port numbers (fit in a 16-bit unsigned field) in
1159           "port" filters
1160         Reject attempts to put savefiles into non-blocking mode
1161         Check for "no such device" for the "get the media types" ioctl
1162           in *BSD

1188         Update Endace DAG and ERF support
1189         Add support for shared libraries on Solaris, HP-UX, and AIX
1190         Build, install, and un-install shared libraries by default;
1191           don't build/install shared libraries on platforms we don't support
1192         Fix building from a directory other than the source directory
1193         Fix compiler warnings and builds on some platforms
1194         Update config.guess and config.sub
1195         Support monitor mode on mac80211 devices on Linux
1196         Fix USB memory-mapped capturing on Linux; it requires a new DLT_
1197           value
1198         On Linux, scan /sys/class/net for devices if we have it; scan
1199           it, or /proc/net/dev if we don't have /sys/class/net, even if
1200           we have getifaddrs(), as it'll find interfaces with no
1201           addresses
1202         Add limited support for reading pcap-ng files
1203         Fix BPF driver-loading error handling on AIX

1208         Hyphenate "link-layer" everywhere
1209         Add /sys/kernel/debug/usb/usbmon to the list of usbmon locations
1210         In pcap_read_linux_mmap(), if there are no frames available, call
1211           poll() even if we're in non-blocking mode, so we pick up
1212           errors, and check for the errors in question.
1213         Note that poll() works on BPF devices is Snow Leopard
1214         If an ENXIO or ENETDOWN is received, it may mean the device has
1215           gone away.  Deal with it.
1216         For BPF, raise the default capture buffer size to from 32k to 512k
1217         Support ps_ifdrop on Linux

1222           buffer size combinations
1223         Update pcap-config so that it handles libpcap requiring
1224           additional libraries

1233         Add link-layer types for DECT
1234         Autoconf fixes (AIX, HP-UX, OSF/1, Tru64 cleanups)
1235         Install headers unconditionally, and include vlan.h/bluetooth.h if
1236           enabled
1237         Autoconf fixes+cleanup
1238         Support enabling/disabling bluetooth (--{en,dis}able-bluetooth)

1241           creation failed)
1242         Fix handling of 'any' device, so that it can be opened, and no longer
1243           attempt to open it in Monitor mode
1244         Add support for snapshot length for USB Memory-Mapped Interface
1245         Fix configure and build on recent Linux kernels
1246         Fix memory-mapped Linux capture to support pcap_next() and
1247           pcap_next_ex()
1248         Fixes for Linux USB capture
1249         DLT: Add DLT_LINUX_EVDEV

1270         Fix dynamic library support on OSX
1271         Return PCAP_ERROR_IFACE_NOT_UP if the interface isn't 'UP', so applications
1272          can print better diagnostic information
1273         Return PCAP_ERROR_PERM_DENIED if we don't have permission to open a device, so
1274          applications can tell the user they need to go play with permissions
1275         On Linux, ignore ENETDOWN so we can continue to capture packets if the
1276          interface goes down and comes back up again.

1420
1421 Tuesday January 9, 2001. guy@alum.mit.edu. Summary for 0.6 release
1422
1423         New Linux libpcap implementation, which, in 2.2 and later
1424         kernels, uses PF_PACKET sockets and supports kernel packet
1425         filtering (if compiled into the kernel), and supports the "any"
1426         device for capturing on all interfaces.  Cleans up promiscuous
1427         mode better on pre-2.2 kernels, and has various other fixes
1428         (handles 2.4 ARPHRD_IEEE802_TR, handles ISDN devices better,
1429         doesn't show duplicate packets on loopback interface, etc.).
1430
1431         Fixed HP-UX libpcap implementation to correctly get the PPA for
1432         an interface, to allow interfaces to be opened by interface name.
1433
1434         libpcap savefiles have system-independent link-layer type values
1435         in the header, rather than sometimes platform-dependent DLT_
1436         values, to make it easier to exchange capture files between
1437         different OSes.
1438
1439         Non-standard capture files produced by some Linux tcpdumps, e.g.
1440         the one from Red Hat Linux 6.2 and later, can now be read.
1441
1442         Updated autoconf stock files.
1443
1444         Filter expressions can filter on VLAN IDs and various OSI
1445         protocols, and work on Token Ring (with non-source-routed
1446         packets).
1447
1448         "pcap_open_dead()" added to allow compiling filter expressions
1449         to pcap code without opening a capture device or capture file.
1450
1451         Header files fixed to allow use in C++ programs.
1452
1453         Removed dependency on native headers for packet layout.
1454         Removed Linux specific headers that were shipped.
1455
1456         Security fixes: Strcpy replaced with strlcpy, sprintf replaced
1457         with snprintf.
1458
1459         Fixed bug that could cause subsequent "pcap_compile()"s to fail
1460         erroneously after one compile failed.
1461
1462         Assorted other bug fixes.
1463
1464         README.aix and README.linux files added to describe
1465         platform-specific issues.
1466
1467         "getifaddrs()" rather than SIOCGIFCONF used, if available.
1468

1477
1478 Assar Westerlund  <assar@sics.se>
1479 - Building outside the source code tree fixed.
1480 - Changed to write out time stamps with 32-bit seconds and microseconds
1481   fields, regardless of whether those fields are 32 bits or 64 bits in
1482   the OS's native "struct timeval".
1483 - Changed "pcap_lookupdev()" to dynamically grow the buffer into which
1484   the list of interfaces is read as necessary in order to hold the
1485   entire list.
1486
1487 Greg Troxel <gdt@ir.bbn.com>
1488 - Added a new "pcap_compile_nopcap()", which lets you compile a filter

1564
1565 - Fixed Linux networking include files to use ints instead of longs to
1566   avoid problems with 64 bit longs on the alpha. Thanks to Cristian

1706
1707 - Hack around deficiency in Ultrix's make.
1708
1709 - Fix two bugs related to the Solaris pre-5.3.2 bufmod bug; handle
1710   savefiles that have more than snapshot bytes of data in them (so we
1711   can read old savefiles) and avoid writing such files.
1712
1713 - Added checkioctl which is used with gcc to check that the
1714   "fixincludes" script has been run.
