	* lisp.h (shut_down_emacs): Doc fix.

	* s/irix4-0.h: Get rid of our fake definitions for setpgrp and
	getpgrp.
	* callproc.c (Fcall_process): Go ahead and use the USG calling
	convention for setpgrp.
	* ymakefile (pre-crt0.o): Add rule for this.  Perhaps it will help
	separate-source-directory compilation.
	* emacs.c (shut_down_emacs): Some USG systems #define
	EMACS_HAVE_TTY_PGRP; call getpgrp as appropriate for such systems.
	* sysdep.c (sys_suspend): Call getpgrp as appropriate for USG and
	non-USG.
	* process.c [IRIX] (create_process): Don't put child in process
	group zero before opening the tty; Irix is like USG in this
	regard.

	Glickstein <bobg@zindigo.z-code.com>:
	* m/iris4d.h (LIB_STANDARD): Do list -lbsd here.
	* s/irix4-0.h (getpgrp, setpgrp): #define these to call BSDgetpgrp
	and BSDsetpgrp.
	(GETPGRP_NO_ARG): Don't #define this.
	* emacs.c (main): Don't test GETPGRP_NO_ARG.
	* sysdep.c (sys_suspend): Don't test GETPGRP_NO_ARG.

(Fkill_emacs, fatal_error_signal): Pass new arg.

(main) [GETPGRP_NO_ARG]: Really pass no arg to getpgrp.

	* sysdep.c [BSD] (inherited_pgroup): New variable.
	(narrow_foreground_group, widen_foreground_group): New functions.
	(init_sys_modes): Call narrow_foreground_group.
	(reset_sys_modes): Call widen_foreground_group.
	* emacs.c [BSD] (inherited_pgroup): Add extern declaration.
	[BSD] (main): Set inherited_pgroup, and put ourselves in our own
	pgroup.

(main) [BSD]: Delete the setpgrp (both times).

(shut_down_emacs): Maybe close X connection here.  New arg NO_X.
(Fkill_emacs): Don't close it here.  Pass new arg.
(fatal_error_signal): Pass new arg.

	* sysdep.c (sys_siglist): Don't define this if HAVE_SYS_SIGLIST is
	#defined.  That lets the system provide it, if it has it.
	* syssignal.h (sigmask): Only define this if <signal.h> hasn't
	given us a definition already.
	* syssignal.h (sys_sigpause): Fix argument in prototype.
	* sysdep.c (init_signals): The masks are called empty_mask and
	full_mask, not signal_empty_mask and signal_full_mask.
	(signal_handler_t): Moved ....
	* syssignal.h: ... to here.
	* systty.h (EMACS_SET_TTY_PGRP): Call tcsetpgrp with the correct
	arguments.
	* emacs.c (main): Don't try to establish signal handlers for
	SIGBUS and SIGSYS unless they're actually #defined.

	':' elsewhere, just have it default to ':' if not #defined, and
	#define it to be ',' in s/vms.h; OS/2 will need it to be ';'.
	* s/vms.h (SEPCHAR): #define this to be ','.
	* s/template.h (SEPCHAR): Mention this.

	Changes for Emacs 19 from Thorsten Ohl <ohl@chico.harvard.edu>:
	* s/mach2.h: copied from the Emacs 18.59 distribution.
	Don't define NO_REMAP, define START_FILES as
	`pre-crt0.o' instead.  Define LIB_MATH as `-lm', to override the
	default `-lm -lc' (there is no libc on the NeXT).
	* ymakefile (STARTFILES): Allow config.h to set this value even if
	ORDINARY_LINK is defined.
	* unexnext.c: Fix subdirectories for the machine dependent include
	files for NeXTStep 3.0; #include <mach/mach.h> and
	<mach-o/loader.h> instead of <mach.h> and <sys/loader.h>.
	(getsectbyname): Remove prototype for this; the system #include
	files take care of that.
	(malloc_cookie): New variable.
	(unexec_doit): Set malloc_cookie to the result returned by
	malloc_freezedry.
	* emacs.c (main): Declare malloc_cookie to be extern, so that we can
	get the value set when we dumped and pass it to malloc_jumpstart.
	* systime.h: The NeXT has a timezone function.

	This isn't specific to X, and it allows us to avoid #including
	xterm.h in files that don't really have anything to do with X.
	* blockinput.h: New file.
	* xterm.h (BLOCK_INPUT, UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT,
	UNBLOCK_INPUT_RESIGNAL): These are now in blockinput.h.
	(x_input_blocked, x_pending_input): Deleted; there are analogs
	in blockinput.h called interrupt_input_blocked and
	interrupt_input_pending.
	* keyboard.c (interrupt_input_blocked, interrupt_input_pending):
	New variables, used by the macros in blockinput.h.
	* xterm.c: #include blockinput.h.
	(x_input_blocked, x_pending_input): Deleted.
	(XTread_socket): Test and set interrupt_input_blocked and
	interrupt_input_pending instead of the old variables.
	* alloc.c, xfaces.c, xfns.c, xmenu.c, xselect.c, keymap.c:
	#include blockinput.h.
	* eval.c: #include blockinput.h instead of xterm.h.
	* keyboard.c: #include blockinput.h.
	(input_poll_signal): Just test
	interrupt_input_blocked, instead of testing HAVE_X_WINDOWS and
	x_input_blocked.

	Block the processing of interrupt input while we're manipulating the
	malloc heap.
	* alloc.c: (xfree): New function, to make it easy to free things
	safely.
	(xmalloc, xrealloc): Block X input while doing the deed.
	(VALIDATE_LISP_STORAGE, gc_sweep, compact_strings): Use xfree
	instead of free.
	(uninterrupt_malloc): New function, to install input-blocking
	hooks into the GNU malloc routines.
	* emacs.c [not SYSTEM_MALLOC] (main): Call uninterrupt_malloc
	on startup.
	* alloc.c: (make_interval, make_float, Fcons, Fmake_vector,
	Fmake_symbol, Fmake_marker, make_uninit_string, Fgarbage_collect):
	Use xmalloc instead of malloc; don't bother to check if out of
	memory here.
	(Fgarbage_collect): Call xrealloc instead of realloc.
	* buffer.c: Use xmalloc and xfree instead of malloc and free;
	don't bother to check if out of memory here.
	(Fget_buffer_create): Put BLOCK_INPUT/UNBLOCK_INPUT pair around
	calls to ralloc routines.
	* insdel.c: Same.
	* lisp.h (xfree): New extern declaration.
	* xfaces.c (xfree): Don't #define this to be free; use the
	definition in alloc.c.
	* dispnew.c, doc.c, doprnt.c, fileio.c, lread.c, term.c, xfns.c,
	xmenu.c, xterm.c: Use xfree instead of free.
	* hftctl.c: Use xfree and xmalloc instead of free and malloc.
	* keymap.c (current_minor_maps): BLOCK_INPUT while calling realloc
	and malloc.
	* search.c: Since the regexp routines can malloc, BLOCK_INPUT
	while runing them.  #include blockinput.h.
	* sysdep.c: #include blockinput.h.  Call xfree and xmalloc instead
	of free and malloc.  BLOCK_INPUT around routines which we know
	will call malloc.

	ymakefile (keyboard.o, keymap.o, search.o, sysdep.o, xfaces.o,
	xfns.o, xmenu.o, xterm.o, xselect.o, alloc.o, eval.o): Note that
	these depend on blockinput.h.

	(Vinvocation_name): New variable.
	(init_cmdargs): Set it.
	(syms_of_emacs): defsubr Finvocation_name, staticpro and
	initialize Vinvocation_name.
	* lisp.h (Vinvocation_name): New extern declaration.
	* xterm.c (invocation_name): Variable deleted; use
	Vinvocation_name now.
	(x_text_icon, x_term_init): Use Vinvocation_name now instead of
	invocation_name.
	(x_term_init): Don't initialize invocation_name.
	(syms_of_xterm): Don't initialize or staticpro invocation_name.
	* xfns.c (invocation_name): Remove extern declaration for this.
	[HAVE_X11] (Fx_get_resource): Use Vinvocation_name now instead of
	invocation_name.
	[not HAVE_X11] (Fx_get_default): Same.

	__do_global_dtors, __CTOR_LIST__, __DTOR_LIST__, __main): Don't
	define these if ORDINARY_LINK is #defined; in that case, the
	standard linking procedure will find definitions for these.

	* emacs.c (main): SIGIOT isn't defined on all systems; don't set
	its signal handler unless it is.

	to deliver it to ourselves. #include "syssignal.h" to get the
	right definitions.

	Vprocess_environment to its own function.
	(set_process_environment): This is that.
	* emacs.c (main): Call set_process_environment earlier than
	init_callproc.

	(fatal_error_signal, Fkill_emacs): Call it, instead of writing it out.
	* xterm.c (x_connection_closed): Call shut_down_emacs instead of
	Fkill_emacs; the latter will try to perform operations on the X
	server and die a horrible death.
	* lisp.h (shut_down_emacs): Add extern declaration for it.

	HAVE_X_WINDOWS in conditionals around the call to syms_of_xmenu.

	(main): Use nice, not setpriority; we just need a
	simple, portable call to nice here.

Eliminate HIGHPRI as compilation option.
(emacs_priority): New C variable, also Lisp variable.
(main): Set the priority iff emacs_priority is nonzero.

(__do_global_ctors, __do_global_ctors_aux): New dummy fns.
(__CTOR_LIST__, __DTOR_LIST__): New dummy variables.

(__CTOR_LIST__, __DTOR_LIST__): New dummy variables.

	* emacs.c (Fkill_emacs): Doc fix.
	(syms_of_emacs): Doc fix for Vkill_emacs_hook.

	MULTI_FRAME is not defined, it still provides the Fframe_width,
	Fframe_height, Fset_frame_width, and Fset_frame_height functions.
