From 8f2eba6efa236376dc3e15723714d39999652408 Mon Sep 17 00:00:00 2001
From: Eli Zaretskii <eliz@gnu.org>
Date: Wed, 15 Mar 2000 12:05:59 +0000
Subject: [__GO32__]: Include <pc.h>. Declare _rl_redisplay_after_sigwinch.
 [__DJGPP__]: Don't declare term_buffer and term_string_buffer (they are
 unused.) (_rl_get_screen_size) [__DJGPP__]: Call ScreenRows and ScreenCols.
 (_rl_init_terminal_io) [__GO32__]: Don't call them here.  Instead, call
 _rl_get_screen_size.  Set terminal_name.  Return 0, to be consistent with the
 function's declaration. (ding) [__GO32__]: Support visual bell by calling
 ScreenVisualBell.
