 475. APM driver:
      . improved clock parameter calculation.
      . Fixed order of initialization of cursor.
      . Fixed restauration of grapical text mode.
      . Added YUY2 video format.
      . Corrected accel framebuffer pitches and max screen height
      (BugzillaR #528, Egbert Eich).
 474. Moved DisableMMIO() out of the unmap() function, added call to
      EnableMMIO() to EnterVT() to work around lockup problems when
      switching between two Xserver (BugzillaR #748, Egbert Eich).
 473. Fixed problem with text widget in Xaw when widget has a different
      depth than the default visual (Bugzilla #745, Wolfram Gloger).
 472. Fixed Sig11 when calling X -query with no ipv6 support in kernel
      (BugzillaR #737, Egbert Eich).
 471. Added support for Sparc64 and AMD64 on FreeBSD.
      This patch also disables warnings from system headers, fixes some elf
      relocations also relevant for other platforms and disables translation of
      KEY_SysReqest and KEY_Break on sparc64. (Bugzilla #739, Eric Anholt).
 470. Switched VIA video driver to fillkey helper function (Bugzilla #525,
      Alan Cox).
 469. Fixed CRT modes > FP panel size for siliconmotion (Bugzilla #727,
      Hugues Fournier).
 468. Fixed xedit coredumps: update counter of free objects when getting an
      object from the list (BugzillaR #722, Egbert Eich).
 467. Fixed definititon of UseInstalledOnCrossCompile so that it never is
      undefined (Harlod L. Hunt II).
 466. Add the 'b' flag to fopen() when opening binary xkm files. This is
      irrelevant for *nix OSes, but reqired for Cygwin. (Bugzilla #689,
      Harold L Hunt II).
 465. Cygwin:
      * MultiWindow Mode: Automatically validate the size of windows that are
        being resized.  (Earle F. Philhower III)
      * Safely shutdown the MultiWindow Mode and Clipboard Manager threads on
        server shutdown.  (Earle F. Philhower III)
      * MultiWindow Mode - Fix a crash from a string copy bug.
        (Earle F. Philhower III)
      * Add lots of defaults for keyboardlayout.  (Alexander Gottwald)
      * Add a system tha allows arbitrary commands to be added to the tray menu
        icon.  (Earle F. Philhower III)
      * Print the name of the keyboardlayout to aid in adding more layouts.
        (Alexander Gottwald)
      * Stop printing the IDirectDrawSurface4_Blt() failure messages after 10
        times.  (Harold L Hunt II)
      * Disable check for pc105 keyboard and just assume that it is present.
        This check was causing problems with certain keyboard drivers that
        failed to report that a pc105 keyboard was present.
	(Alexander Gottwald)
      * MultiWindow Mode - Add handling for WM_CHANGE_STATE IconicState
        messages;
      minimize the associated Windows window when these messages are
      received. (Harold L Hunt II).
      Submitted: (Bugzilla #704, Harold L. Hunt).
 464. cygwin.cf:
      * removed BuildDPS flag.
      * Changed Alloca flag as Cygwin 1.5.x supports alloca, now.
      * Use external expat package by default.
      * Changed XawI18nDefines to utilize improved wide char suoort in
      Cygwin 1.5.x. (Bugzilla #699, Harold L. Hunt II).
 463. Fixed C&T panel register setting (Akira Taniguchi, Egbert Eich).
 462. Fixing crash on ia64 because of wrong setjmp buffer alignment (Bugzilla
      #596, John Dennis).
 461. Changing ImPS/2 mouse Z-axis range to -8 to 7 (Bugzilla #691,
      Matthew W. S. Bell, Egbert Eich).
 460. Making sure the compiled xkb config file is found by Xnest if
      ProjectRoot is modified (Bugzilla #688, Frank Giessler).
 459. Fixing build of machine code .S files on OS/2 (Bugzilla #689,
      Frank Giessler).

  - Changed wording of message which is printed by the bigfont extension when
    shm support doesn't exist (Bugzilla #698, Harold Hunt).
