+        * w32.c: Added wrapper functions around the win32 API functions
+        OpenProcessToken, GetTokenInformation, LookupAccountSid, and
+        GetSidIdentifierAuthority.  These wrapper functions serve two
+        purposes:
+        1.  They ensure that the wrapped function can never be called
+        when Emacs is running on an operating system on which they are
+        not supported (Microsoft Windows 95 / 98 / ME).
+        2.  They call the wrapped functions via function pointers rather
+        than calling them directly.  This avoids taking advantage of the
+        undocumented fact that although these functions are not supported
+        in the 9x branch of Microsoft Windows, the functions do exist in
+        the version of advapi32.dll that is found in the 9x branch of
+        Microsoft Windows.
+        This change is part of my fix for the following entry in
+        etc/PROBLEMS: "Emacs built on Windows 9x/ME crashes at startup on
+        Windows XP, or Emacs built on XP crashes at startup on Windows
+        9x/ME."
+
+        * w32.c (init_user_info): Replaced the calls to the win32 API
+        functions OpenProcessToken, GetTokenInformation, LookupAccountSid,
+        and GetSidIdentifierAuthority with calls to the newly added
+        wrapper functions.
+        This change is part of my fix for the following entry in
+        etc/PROBLEMS: "Emacs built on Windows 9x/ME crashes at startup on
+        Windows XP, or Emacs built on XP crashes at startup on Windows
+        9x/ME."
+
+        * w32.h: Added extern declarations for the following functions:
+        syms_of_w32term, syms_of_w32fns, syms_of_w32select,
+        syms_of_w32menu, and void syms_of_fontset.
+        This change is part of my fix for the following entry in
+        etc/PROBLEMS: "Emacs built on Windows 9x/ME crashes at startup on
+        Windows XP, or Emacs built on XP crashes at startup on Windows
+        9x/ME."
+
+        * w32fns.c (w32_wnd_proc): Added code to reinitialize the
+        function pointer track_mouse_event_fn in the handler for the
+        WM_SETFOCUS message.
+        This change is part of my fix for the following entry in
+        etc/PROBLEMS: "Emacs built on Windows 9x/ME crashes at startup on
+        Windows XP, or Emacs built on XP crashes at startup on Windows
+        9x/ME."
+
+        * w32menu.c (initialize_frame_menubar):  Added code to
+        reinitialize the function pointers set_menu_item_info and
+        get_menu_item_info.
+        This change is part of my fix for the following entry in
+        etc/PROBLEMS: "Emacs built on Windows 9x/ME crashes at startup on
+        Windows XP, or Emacs built on XP crashes at startup on Windows
+        9x/ME."
+
+        * sound.c:  Added a partial implementation of play-sound-internal
+        for Microsoft Windows.  Added various #ifdef / #else / #endif
+        code blocks to separate the code that will compile under
+        Microsoft Windows from the code that is specific to Gnu/Linux.
+        Moved several blocks of code around to make this separation of
+        code into Windows compatible and Gnu/Linux compatible code blocks
+        easier.
+
+        * makefile.w32-in: Made modifications so that sound.c would be
+        included in the Windows port of Emacs and that it would link with
+        WinMM.lib.
+
+        * s/ms-w32.h: Defined the symbol HAVE_SOUND so that the newly
+        added support for play-sound-internal under Windows would be
+        included in the build of Emacs.
+
+

         * w32fns.c (w32_load_system_font): Don't disable Cleartype.
