(AC_FUNC_SETPGRP): Add.
* aclocal.m4, configure, config.in: Regenerated.
* inflow.c (gdb_setpgid): Get rid of NEED_POSIX_SETPGID and
SETPGRP_ARGS. Always use setpgid if it is available, fall back on
setpgrp if it isn't. Use SETPGRP_VOID (defined by autoconf) to
distinguish between the two setpgrp flavours.
* config/xm-sysv4.h, config/arm/xm-linux.h,
config/i386/xm-i386aix.h, config/i386/xm-sco.h,
config/i386/xm-linux.h, config/i386/xm-ptx.h,
config/m68k/xm-linux.h, config/powerpc/xm-linux.h,
config/sparc/xm-linux.h, config/sparc/xm-sun4sol2.h,
config/ia64/xm-linux.h (NEED_POSIX_SETPGID): Remove.
* config/rs6000/xm-rs6000.h (SETPGRP_ARGS): Remove.
BROKEN_LARGE_ALLOCA. Do the cleanup before returning, rather than
leaving it on the chain. Reindent much of this function.
* config/sparc/{xm-sun4sol2.h,xm-sun4os4.h},
config/i386/{xm-sun386.h,xm-i386m3.h,xm-i386mach.h},
config/m68k/{sun3os4.h,xm-news.h,xm-hp300hpux.h},
config/ns32k/xm-ns32km3.h: Remove all references to
BROKEN_LARGE_ALLOCA; with the above change it is no longer needed.
* main.c, fork-child.c, many config files: Remove all
SET_STACK_LIMIT_HUGE code; with the above changes it should no
longer be needed.
* symtab.c (lookup_partial_symbol): Use if and abort, not assert.
This avoids __eprintf troubles.
* main.c (main): Surround in #ifndef MAIN_OVERRIDE. Move
initialization code which needs to be called even if we bypass the
command line stuff into gdb_init.
* utils.c (fputs_unfiltered): Surround in #ifndef
FPUTS_UNFILTERED_OVERRIDE.
* Makefile.in (libgdb.a): New target.
* utils.c: Rearrange I/O stuff a bit so that all output goes
through fputs_unfiltered. Use vasprintf; removes arbitrary limit
which made %s not work with arbitrarily large strings.
* printcmd.c (printf_command): Use printf_filtered, not
printf_unfiltered and printf, now that arbitrary limit is gone.
* 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.
m88k, mips, none, ns32k, pa, pyr, romp, rs6000, sparc, tahoe, vax,
z8k}: New directories to hold cpu specific configuration files.
Naming follows gcc convention.
* config/{*.mt, *.mh}: All target and host makefile fragment
config files moved to an appropriate config/<cpu> subdirectory.
