From c2e247c4ff760324df53fe50a9ef9168fd5e9452 Mon Sep 17 00:00:00 2001
From: Jim Kingdon <jkingdon@engr.sgi.com>
Date: Wed, 30 Jun 1993 22:20:53 +0000
Subject: 	* inftarg.c: Remove unused include of terminal.h. 	*
 signals.h: Don't undefine signals anymore. 	* main.c: Use job_control from
 serial.h. 	* fork-child.c (fork_inferior): Use gdb_setpgid. 	*
 serial.h, ser-unix.c, ser-go32.c: Provide gdb_setpgid. 	* utils.c
 (quit): Use current_target->to_terminal_ours to figure 	out whether we
 care about lack of job control, rather than __GO32__. 	* utils.c: Include
 serial.h not terminal.h 	(quit): Use job_control not TIOCGPGRP. 	*
 terminal.h: Don't undefine TIOCGPGRP. 	* serial.h, ser-unix.c, ser-go32.c,
 ser-tcp.c: Add SERIAL_FLUSH_OUTPUT. 	* utils.c (quit): Use it. 	*
 serial.h: Add SERIAL_UN_FDOPEN. 	* utils.c (quit): Use it. 	*
 ser-unix.c: Add process group to ttystate. 	[HAVE_SGTTY]: Add tchars,
 ltchars, and lmode to ttystate. 	* inflow.c: Include serial.h not
 terminal.h. 	Use serial.h stuff to replace most of the maze of #ifdef's. 
 * inflow.c, main.c, inferior.h: make gdb_has_a_terminal a function. 	*
 serial.h: Document SERIAL_SET_TTY_STATE as being immediate. 	* ser-unix.c:
 Use TIOCSETN not TIOCSETP so it is true. 	* serial.h, ser-unix.c,
 ser-go32.c, ser-tcp.c: 	Add SERIAL_PRINT_TTY_STATE,
 SERIAL_NOFLUSH_SET_TTY_STATE, and 	SERIAL_SET_PROCESS_GROUP. 	*
 inflow.c: Use them. 	* config/xm-svr4.h, config/rs6000/xm-rs6000.h,
 config/sparc/sun4os4.h: 	Define HAVE_TERMIOS. 	* Various: Remove all
 use of TIOC*_BROKEN.
