+        * xfaces.c, xdisp.c, window.c, w32xfns.c, w32term.h, w32term.c,
+        w32select.h w32select.c, w32proc.c, w32menu.c, w32inevt.c,
+        w32help.c, w32font.c, w32font.c, w32fns.c, w32console.c, w32.h,
+        w32.c, unexw32.c, termhooks.h, process.c, menu.c, keyboard.h,
+        keyboard.c, image.c, frame.h, frame.c, fontset.c, font.h, font.c,
+        emacs.c, dispextern.h, cygw32.h, cygw32.c, conf_post.h,
+        Makefile.in: use HAVE_NTGUI for W32 GUI and WINDOWSNT for the
+        operating system.  defined(HAVE_NTGUI) && !defined(WINDOWSNT) is
+        now a supported configuration.
+
+        * Makefile.in: consolidate image variables into LIBIMAGE; add
+        W32_OBJ and W32_LIBS. Compile new files.
+
+        * conf_post.h:
+        (_DebPrint) declare tracing facility for W32 debugging.  We need
+        to unify tracing later.
+
+        (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
+        unconditional use of W32 Unicode functions.  Cygwin runs only on
+        100% Unicode operating systems.
+
+        * cygw32.c: New file.  Define Cygwin-specific facilities.
+        (Fcygwin_convert_path_to_windows)
+        (Fcygwin_convert_path_from_windows): New user functions for
+        accessing Cygwin path-munging routines.
+
+        * cygw32.h: New file.
+        (WCSDATA, to_unicode, from_unicode): Define facilities for storing
+        UTF-16LE strings temporarily inside non-Lisp-visible string
+        objects.
+
+        (w32_strerror): Just what it says on the tin.
+
+        * emacs.c: Make the NS fork-then-exec code for daemon-launching
+        also run for Cygwin; both systems have the same problem with using
+        GUI facilities in a forked child.  Also call syms_of_cygw32,
+        syms_of_w32select in correct places.
+
+        (DAEMON_MUST_EXEC): new macro defined to signal that a platform
+        needs fork-then-exec for daemon launching.
+
+        * font.h: Include frame.h.
+
+        * image.c: Use the image library cache machinery only when we're
+        compiling for native WINDOWSNT; Cygwin can use shared libraries
+        like any other Unixlike system.
+
+        * keyboard.c: Clarify a comment regarding the input loop.
+
+        * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
+        functions directly instead of trying to detect at runtime that our
+        host operating system supports them.  We make this change for two
+        reasons: Cygwin lacks support for the multibyte character
+        conversion functions used by the legacy menu code, and Cygwin
+        never needs to rely on non-Unicode APIs.
+
+        * unexw32.c (hinst): Declare extern.
+
+        * w32.c: Change header order;
+        (w32_strerror): Move to w32fns.c because we need it for
+        non-WINDOWSNT builds.
+
+        * w32.h: Add #error macro to make sure we don't include w32.h for
+        Cygwin builds.  Remove w32select declarations.
+
+        * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
+        w32fns.c. w32console.c is WINDOWSNT-only.
+
+        * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
+        NTGUI_UNICODE tweaks.  (See above.) Change _snprintf to the more
+        POSIXy alternative.
+        (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
+        (w32_major_version, w32_minor_version, w32_build_number)
+        (os_subtype, sound_type): Define here
+        (w32_defined_color): Make color parameter const for consistency
+        with other _defined_color functions.
+        (w32_createwindow): Unconditionally call w32_init_class instead of
+        doing so only when hprevinst is non-NULL.  Plumbing hprevinst
+        through the code is complex and unnecessary because class
+        registration is practically free.
+        (w32_name_of_message): New EMACSDEBUG-only function.
+        (Fset_message_beep): Move here
+        (Fx_open_connection): Require that the display name for Windows be
+        "w32" for consistency, emacsclient disambiguation, and maybe, one
+        day, multi-window-system support.
+        (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
+        Cygwin files for W32 GUI facilities, since these clearly don't
+        expect Cygwin names.
+        (_DebPrint): Define.
+        (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
+        (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
+        (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
+        (w32_last_error): Remove.
+
+        * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.
+
+        * w32heap.c (syspage_mask): Declare here.
+        (cache_system_info): Remove.
+
+        * w32inevt.c (faked_key): Define globally, not statically.
+        (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
+        (w32_console_toggle_lock_key): Move to w32fns.c.
+
+        * w32menu.c: Include setjmp.h.  NTGUI_UNICODE changes throughout.
+
+        * w32proc.c (_DebPrint): Move to w32fns.c.
+        * w32select.c: Include string.h, stdio.h for Cygwin.
+        * w32select.h: New File.
+
+        * w32term.c: Include io.h for non-CYGWIN builds; needed for
+        get_osfhandle.
+        (w32_message_fd): New variable.  Under Cygwin, holds the file
+        descriptor the system used to tell us about pending thread
+        messages.
+
+        (w32_init_term): Remove incorrect calls to fcntl and init_sigio
+        that prevented compilation under non-WINDOWSNT systems.
+
+        (w32_initialize): Open /dev/windows and assign it to
+        w32_message_fd.  Provide w32 feature.
+
+        * w32term.h: Include frame.h, atimer.h.  Declare various frame functions.
+        (WM_EMACS_INPUT_READY): add.
+        (prepend_msg, w32_message_fd): Declare globally.
+
+        * w32xfns.c:
+        (keyboard_handle): Use only when WINDOWSNT.
+        (notify_msg_ready): New function.  Posts a message to the main
+        thread's message queue under CYGWIN, which wakes up the main
+        thread from select(2) by making the /dev/windows file descriptor
+        ready.  Under WINDOWSNT, it sets an event the same way the old
+        code did.
+
+        (post, prepend_msg): Actually call notify_msg_ready instead of
+        setting the input event directly.

         * ralloc.c (relinquish): If a heap is ready to be relinquished,
