post-4.8.0 platform-related updates:

   4. Enable HasLibPthread for FreeBSD 7 and later because libc_r is no
      longer present, and was deprecated since some earlier release (6.x?)
      (David Dawes).
   3. Disable optimisation when building the scanpci/pcidata modules which
      contain a large amount of statically initialised data.  Optimisation
      is disabled because it provokes an internal compiler error on FreeBSD
      7.0 (David Dawes).
   2. Update Xinstall.sh version for 4.8.0, and recognise some newer platforms
      and their bindists (David Dawes).
   1. Elf has been the only supported format on FreeBSD for a long time.
      The objformat utility has been deprecated for a long time, and was
      finally removed in FreeBSD 7.  Don't call it from imake for FreeBSD
      5.x and later (David Dawes).

Prepare for tomorrow's tagging of 4.8.0

Snapshot: 4.7.99.31

  69. Fix error path in -configure processing.  (Matthieu Herrb)

Snapshot: 4.7.99.30

Snapshot: 4.7.99.29

  68. Move CloseWellKnownConnections() calls into OsCleanup(TRUE) calls.

      (Marc La France).

Snapshot: 4.7.99.28

Typos

  67. When using BSD authentication in xdm, wipe out the password as soon as
      possible to prevent it from showing up in the address space of
      subsequently forked child processes (Matthieu Herrb).
  66. Ensure XVidModeGetMonitor() always returns dynamically allocated data, as
      documented in its man page (Marc La France).
  65. Fix potential crash in DBE (Dave Arlie).
  64. Import X.Org fixes for CVE-2008-1377, CVE-2008-1379, CVE-2008-2360 and
      CVE-2008-2361 security advisories.
  63. Various x86emu changes:
      - Fix various halfword overflow issues (Scitech).
      - Add RDTSC emulation (Aaron Plattner).
      - Fix JNL emulation (David Wong).
      - Add emulation of CPUID, levels 0 & 1.  If the host architecture
        supports CPUID, pass that implementation's results to the emulation.
        If running on a 386 or 486 that does not support CPUID, provide a
        reasonable simulation (instead of SIGILL'ing).  On all other host
        architectures, the emulator will report itself as a 486DX
        (Marc La France).
      - Add BTS emulation (Felix Kuehling).
      - Fix BSF & BSR emulations (Aaron Plattner).
      - Fix MUL and IMUL emulations in the 64-bit case (Matthias Hopf).
  62. xf86sym.c build fix when RandR is disabled (Pat Kane, Bugzilla #1693).
  61. Spruce up implementation of pthread_key_create(), pthread_key_delete()
      pthread_getspecific() and pthread_setspecific() stubs in libXThrStub
      library.  Inspired by a change found in OpenBSD repository
      (Marc La France).
  60. When opening display, if LOCALCONN fails, fall back to UNIXCOMM, then
      TCPCONN (Alex Chen).
  59. Improve uniqueness of XDM-AUTHORIZATION-1 cookies.  (Egbert Eich).
  58. Fix possible segfault when using XDM-AUTHORIZATION-1 keys for remote
      clients over IPv6.  (Christian Weisgerber)

      data.  (Dick Wesseling, Bugzilla #1691).

Snapshot: 4.7.99.21

  56. Allow 32-bit PCI I/O addresses on Linux/PowerPC (Marc La France).

      #39  (Marc La France).

Snapshot: 4.7.99.20

  54. Fix possible reference to freed memory in HP ZX1 PCI chipset scan and
      emulate configuration space more closely for its fake bridges
      (Marc La France).

Typos

  53. Fix bug that caused the PCI scan to ignore bus segments that are known to
      before the scan starts  (Marc La France).

Snapshot: 4.7.99.19

Snapshot: 4.7.99.18

  52. Fix radeon driver to not relocate the framebuffer within its aperture on
      non-DRI platforms.  Fixes a SunOS/sparc panic upon /dev/console (or
      /dev/wscons) output while the server is running.  (Marc La France).

  51. Change atimisc to not disable the MMIO area at the tail end of the linear
      aperture if it is found to be enabled on entry.  Fixes a hang on
      Solaris/sparc upon /dev/console or /dev/wscons output while the server is
      running (Marc La France).

  50. Change the aperture driver for Solaris to makr its mappings as non-
      cacheable and as having sideeffects  (Marc La France).

  49. Avoid unpredictable behaviour on PCI-X and/or PCI Express capable ix86,
      x86_64 and PowerPC systems  (Marc La France).

Snapshot: 4.7.99.17

  48. Fix ATIPreInit() glitch that caused it to ignore the posiibility that the
      common layer had relocated a Mach64's PCI block I/O base
      (Marc La France).

  47. Disable Mach64 hardware cursors when the unaccelerated VGA CRTC is used
      to produce server-generated video modes (Marc La France).
  46. Fix Mach64 video memory burst transfers on x86_64 (Marc La France).

  45. Remove two unused functions from xf4bpp (Miod Vallat, Marc La France).

  44. Fix additional incorrect assumptions regarding unassigned PCI resources
      (Marc La France).

  43. Mitigate brokenness in /dev/console redirection on Solaris.  Should this
      redirection fail, redirect the server's stderr to the log to avoid screen
      corruption due to the server's own console output.  (Marc La France).

  42. Add a few more Radeon PCI IDs (prompted by Loic Mahe).  Also, remove the
      tracking of these from the "ati" module.  (Marc La France)

... and fix typo in CHANGELOG entry 34.

  41. On SunOS, add a command line flag to disable the server's /dev/console
      redirection  (Marc La France).

  40. Rework the handling of unassigned PCI resources in the server to ensure
      they are reassigned while the server is running and restore them to their
      unassigned state on server exit  (Marc La France).

  39. Change the scanpci and pcitweak utilities to simulate a completed master
      abort instead of reading PCI register 0xb8 of Sun's Simba PCI-to-PCI
      bridges, as reads of this register cause a PCI interrupt acknowledge
      cycle on the secondary bus for an interrupt that did not actually occur.
      Note that no other code touches this register.  (Marc La France).

  38. Avoid screen corruption that occurs upon /dev/console output while the
      X server is running on SunOS, by redirecting this output into a file.
      The file is copied back to /dev/console on server exit.  Note that screen
      corruption still occurs on output to /dev/wscons because wscons cannot be
      redirected in this fashion.  (Marc La France).

Snapshot: 4.7.99.16

Snapshot: 4.7.99.15

  37. Radeon driver changes:
      - Merge in various changes from X.Org, via OpenBSD's xenocara repository.
        Among other things, this adds support for newer Radeon's.
      - Don't use vgaHW if the video mode on server entry is found to be an
        accelerator (i.e. non-VGA) video mode (Marc La France).
      - Avoid hard-failed master aborts while attempting to read video BIOS
        (Marc La France).

  36. Rage 128 driver changes:
      - Add support for dual head on Rage 128 Mobility's (X.Org, via OpenBSD's
        xenocara repository).
      - Don't use vgaHW if the video mode on server entry is found to be an
        accelerator (i.e. non-VGA) video mode (Marc La France).
      - Avoid hard-failed master aborts while attempting to read video BIOS
        (Marc La France).

  35. Fix PCI resource relocation to avoid nullifying resources
      (Marc La France).
  34. In int10, do attempt to populate shadow system BIOS segments if there's
      a risk of hard-failed master aborts (Marc La France).

Add missing CHANGELOG entry ...

  32. Temporarily ignore 64-bit PCI memory address spaces on SPARC
      (Marc La France).
  31. For fault isolation purposes, on SPARC, bracket all PCI configuration
      space accesses with MEMBAR's  (Marc La France).
  30.5.  Change PCI scan to mitigate the effects of PCI Express Unsupported
      requests (its idea of PCI's master aborts).  On Solaris/SPARC at least,
      this tones down a system freeze to a SIGKILL of the PCI scan.
      (Marc La France).
  30. Add PCI-X and PCI Express to the mix of PCI variants that are supported
      in a single system.  Includes, but is not limited to, support for Sun's
      Ultra 25 and Ultra 45 systems.  (Marc La France).
  29. Remove assumption that all PCI entities have a function 0
      (Marc La France).

  32. Zero out all SPARC SunOS framebuffers on server exit (Marc La France).

  32. Temporarily ignore 64-bit PCI memory address spaces on SPARC
      (Marc La France).
  31. For fault isolation purposes, on SPARC, bracket all PCI configuration
      space accesses with MEMBAR's  (Marc La France).
  30. Add PCI-X and PCI Express to the mix of PCI variants that are supported
      in a single system.  Includes, but is not limited to, support for Sun's
      Ultra 25 and Ultra 45 systems.  (Marc La France).
  29. Remove assumption that all PCI entities have a function 0
      (Marc La France).

  28. Update to 2008-03-26 pci.ids snapshot.  Also add some more recent PCI
      Radeon IDs.  (Marc La France)

  27. Fix integer wrap-arounds in XAA's wide line code path (Paul Mackerras).
  26. Fix XAA segfault when dealing with certain TE fonts with null glyphs
      (Soran Sandmann Pedersen).

  25. Make some of ATIProbe()'s verbose messages less misleading
      (Marc La France).
  24. Fix reversed memset() arguments in atimisc LUT handling (David Krause).

  23. In favour of the majority case, assume x86 and x86_64 systems cannot
      hard-fail master aborts.  On an experimental basis, also assume the same
      of alpha systems.  This adds support for such systems that don't include
      a PCI-to-ISA bridge.  (Marc La France)

Snapshot: 4.7.99.14

  22. Fix null pointer defereference in XKB when LEDs don't exist
      (Peter Hutterer, via X.Org bug #13961).

  21. Adapt from X.Org fixes for the CVE-2007-5760, CVE-2007-5958,
      CVE-2007-6427, CVE-2007-6428, CVE-2007-6429 and CVE-2008-0006 security
      advisories.

  20. Remove unnecessary #include of <linux/config.h> from our Linux DRM
      source  (Bugzilla #1689, Marc La France).

  19. When building an XFree86 loader server with stack backtrace support, use
      GCC's -fno-omit-frame-pointer flag to improve the accuracy of stack
      traces (Marc La France).
  18. Fix (portably this time) X server links to ensure dependant subdirs are
      tranversed before the server linked  (Marc La France).

Snapshot: 4.7.99.7

Snapshot: 4.7.99.6

Snapshot: 4.7.99.5

  15. Do not free all Mesa buffers upon GLX extension closedown.  Instead these
      will be freed later, when FreeAllResources() is called to also free the
      drawable privates that reference these buffers.  Fixes Bugzilla #1685
      (Marc La France).
  14. Fix Mesa to complain (on stderr), rather than segfault, when an attempt
      is made to free an unknown buffer (Marc La France).

      "/." from its "from" argument (Marc La France).

   2. On SVR4 variants (including SunOS & Solaris), use the `make`
      implementation found in $PATH, instead of a hard-wired one
      (Marc La France).

   1. Remove (what's left of) the build's dependencies on the Glide2 and Glide3

Snapshot: 4.6.99.24

Fix attribution

 150. Fix build with an external freetype2 library (both newer and older than
      the version we provide under xc/extras/).  However, still build
      libXfont's FreeType backend module with the freetype2 version we provide
      because it is the only version known to be modified to correctly build
      the module (Jie Luo, Marc La France).

      CVE-2007-1003, CVE-2007-1351, CVE-2007-1352 and CVE-2007-1667
      (Josh Bressers, Chris Evans, Sean Larsson, iDefense, Matthieu Herrb,
      Marc La France).

 131. Fix installation of xkbcomp 'dir' files  (Marc La France).

 130. Prevent the IRIX compiler's use of its intrinsic builtin functions as
      many of them are buggy (an understatement) (Marc La France).

 129. Add a rewrite of Mark Vojkovich's restest utility that avoids deadlocks
      by buffering data and delaying its display until after the server is
      ungrabbed (Marc La France).

 128. Update Darwin port with selected changes from X.Org and a liberal
      sprinkling of build fixes (Marc La France, with help from
      Frank J. R. Hanstick).

 127. Re-instate correct decoding of Simba PCI routing on all SPARC OSes
      (Marc La France).
