	only have the h_addr field in their struct hostent.

	* s/template.h: Mention that you should #define HAVE_TERMIO or
	HAVE_TERMIOS, but not both, and that HAVE_TERMIOS is preferred.
	* systty.h (EMACS_SET_TTY_PGRP): Don't assign the return value of
	tcsetpgrp to *pgid; it's just a status value.
	* config.h.in (HAVE_RANDOM): This shouldn't be defined on Linux
	systems using XFree386, and perhaps is inappropriate in general.
	* m/intel386.h: #undefine the integer size macros, since the Linux
	<values.h> file #defines them itself.
	* mem-limits.h (get_lim_data): Linux has the ulimit call; if it
	fails, fall back on ULIMIT_BREAK_VALUE.
	* process.c: Linux needs the WAITTYPE, etc. definitions.
	* unexec.c (hdr, ohdr): Linux has the ordinary `struct exec' type;
	no need to use SYSV names.
	* s/linux.h: New file.

	29th, since that re-introduces the race condition the comments are
	warning about.  Call clear_waiting_for_input before calling
	status_notify, though.

	clear_waiting_for_input when we exit the loop because process
	input has arrived.

	inaccessible.

	Solaris, it's not necessary to check if we should redeliver SIGIO,
	according to David Mackenzie.
	* s/sol2.h: #include "usg5-4.h", and #define const.

call before the set_waiting_for_input call.

	equivalent of /dev/null, and the suffixes used by executable
	files.  This is simple, and helps people porting Emacs to other
	operating systems.
	* process.h (NULL_DEVICE): Give this a default value.
	* process.c (Fstart_process): Pass EXEC_SUFFIXES to openp.
	(Fprocess_send_eof): Use NULL_DEVICE instead of "/dev/null".
	* callproc.c (Fcall_process): Pass EXEC_SUFFIXES to openp.
	Use NULL_DEVICE instead of "/dev/null".

	floating-point as well as integer arguments.  subr.el defines the
	former as an alias for the latter.
	* data.c (Fnumber_to_string): Renamed from Fint_to_string.
	(wrong_type_argument): Adjust caller.
	(syms_of_data): Adjust defsubr.
	* fns.c (concat): Adjust caller.
	* lisp.h (Fnumber_to_string): Adjust extern declaration.
	* mocklisp.c (Finsert_string): Adjust caller.
	* process.c (status_message): Adjust caller.

	(WIFSTOPPED, WIFSIGNALED, WIFEXITED, XRETCODE, WSTOPSIG,
	WCOREDUMP, WTERMSIG): New dummy definitions.
	(deactivate_process): Add missing semicolon.

till a given cons cell has a non-nil car.
Delete vipc conditionals.

	control characters to processes, don't try to return Qnil; just
	return.

	* process.c [! subprocesses] (wait_reading_process_input):
	Remember to re-enable polling for input.

	the sigchld handler clear *input_available_clear_time.
	(wait_reading_process_input): Check for process activity after
	setting the timeout and calling set_waiting_for_input.
	(sigchld_handler): If the process which has exited is one we care
	about, clear *input_available_clear_time.

	* process.c (process_send_signal): Use TERMIOS functions in
	preference to BSD ioctls.  Some systems attempt to provide the BSD
	functions for backward compatibility, and get it wrong.

	had a misplaced paren.  This only became apparent because of
	jimb's change on February 8 to Fexpand_file_name.
	* callproc.c (Fcall_process): Ditto.

	garbaged whenever it goes from invisible to visible.
	* dispextern.h (frame_garbaged): Move extern declaration from here...
	* frame.h (frame_garbaged): ... to here.  The FRAME_SAMPLE_VISIBILITY
	macro uses it now, and this seems to be just as modular.  Make a
	new page, just for this and message_buf_print.
	(struct frame): Doc fix for the `visible' field.
	* process.c: #include "frame.h" instead of "dispextern.h"; the
	only thing we care about from it is the frame_garbaged
	declaration.
	* ymakefile: Note dependency change.

	for subprocesses when the buffer's default-directory is a handled
	name.
	* fileio.c (Funhandled_file_name_directory): New function.
	(Qunhandled_file_name_directory): New file-name-handler operation.
	(syms_of_fileio): Defsubr Sunhandled_file_name_directory, and
	initialize and staticpro Qunhandled_file_name_directory.
	* callproc.c (Fcall_process): Call Funhandled_file_name_directory
	on the buffer's default directory.  Do it earlier in the function
	so there's less to GCPRO.
	* process.c (create_process): Don't check the validity of the
	buffer's default directory here...
	(Fstart_process): Instead, do it here; if we call
	Funhandled_file_name_directory here, there's less GCPROing to do.

	* process.c (wait_reading_process_input): Doc fix.

	Added VMS changes from Roland Roberts.

	* process.c (read_process_output): Save, widen, insert the process
	output, and then restore the restriction if inserting text outside
	the visible region.

	* process.c (Fstart_process): Establish an unwind-protect to
	remove PROC from the process list if an error occurs while
	starting it.
	(start_process_unwind): New function to help with that.
	(create_process): There's no need to explicitly call
	remove_process if the fork fails; the record_unwind_protect in
	Fstart_process will take care of it.

	* process.c (wait_reading_process_input): Test the C preprocessor
	symbol "ultrix", not "__ultrix__" to see if we should ignore
	ENOMEM errors from select.

	* process.c (process_send_signal): On systems which have both
	the TIOCGETC and TCGETA ioctls, just use the former.

	* s/bsd4-2.h, s/bsd4-3.h: #define SIGNALS_VIA_CHARACTERS.
	* process.c (process_send_signal): Put all the code for sending
	signals via characters in a #ifdef SIGNALS_VIA_CHARACTERS.  Decide
	whether to use the Berkeley-style or SYSV-style ioctls by seeing
	which ioctl commands are #defined.

	* process.c (process_send_signal): Doc fix.

	<fcntl.h>.
	(process_send_signal): Don't try to send SIGTSTP
	unless SIGTSTP is defined.

	Lisp_Object at the top of the file.
	(decode_status): Don't untag XCONS (tem)->cdr before storing it in
	tem; tem is a Lisp_Object, too.
	(process_send_signal): Declare this to be static void.  Don't
	return Qnil; nobody cares.
	(sigchld_handler): Use XFASTINT to manipulate p->infd.

	* process.c (pty_process): Variable deleted; it's no longer used.
	(syms_of_process): Don't initialize it.

	ENOMEM, treat that like EINTR under Ultrix.

	(create_process): #if 0 out the code which sets the child's
	handler for SIGCHLD to sigchld; the code which gives sigchld its
	value has been diked out under these CPP symbols, so this should
	be diked out too.

(create_process) [HAVE_SETSID]: Use TIOCSCTTY if exists.

	system doesn't have that facility.

	* process.c: [USG5] Don't include <fcntl.h>.
	[USG] Don't bother including termios, termio, or fcntl; systerm.h
	takes care of all that.
	Remove the "mis;tak-+;;" line from the code; apparently this
	section of code does get used.

	* process.c (wait_reading_process_input): Put comments around
	text following #endif.
