     (cursorY): New functions.
     src/termhooks.h (cursorX, cursorY): Prototypes of functions on
     WINDOWSNT, macros that call curX and curY elsewhere.
     src/termchar.h (struct tty_display_info) <showing_menu>: New flag.
     src/term.c (tty_hide_cursor, tty_show_cursor) [WINDOWSNT]: Call w32
     specific function to hide and show cursor on a text-mode terminal.
     (tty_menu_struct, struct tty_menu_state): New structures.

     of in x-popup-menu.
     (ns_popup_dialog): Adapt order of arguments to the other
     *_menu_show implementations.
     (Fx_popup_dialog): Function deleted.
     src/msdos.c (x_set_menu_bar_lines): Delete unused function.
     src/menu.h (tty_menu_show, menu_item_width): provide prototypes.

     (single_keymap_panes): Use it instead of a compile-time
     conditional.

     of compile-time conditionals.
     (encode_menu_string): New function.
     (list_of_items, list_of_panes): Use it instead of ENCODE_STRING
     the macro, since different types of frame need different encoding

     of, or in addition to, compile-time conditionals.
     (menu_item_width, Fmenu_bar_menu_at_x_y): New functions.

     on a TTY.  Don't barf when invoked on a text-mode frame.  Check

     invoking terminal-specific menu-show functions.  Call
     tty_menu_show on text-mode frames.
     (Fx_popup_dialog): Moved here from xmenu.c.  Test frame types at
     run time to determine which alternative to invoke; support dialogs
     on TTYs.

     <Qecho_keystrokes>: New static variable.

     window-system being available.
     src/editfns.c (Fmessage_box) [HAVE_MENUS]: Don't condition the call
     to x-popup-dialog on the frame type, they all now support popup
     dialogs.
