+ * event-top.c (main_ui_): Delete.
+ (main_ui, current_ui, ui_list): No longer initialize here.
+ * main.c (captured_main): UI initialization code factored out to
+ new new_ui function.
+ (gdb_main): Wrap captured_main with TRY/CATCH instead of
+ catch_errors.
+ * top.c (highest_ui_num): New global.
+ (new_ui): New function.
+ * top.h (struct ui) <num>: New field.
+ (new_ui): New declaration.

* cli/cli-interp.c (cli_on_normal_stop): Bail out early if there's
nothing to print. Use should_print_stop_to_console.
* tui/tui-interp.c (tui_on_normal_stop): Likewise.
