* 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.
