	* editfns.c (Fcurrent_time_zone): Take an optional argument specifying
	what (absolute) time should be used to determine the current time zone.
	Yield just offset and name of time zone, including DST correction.
	Yield time zone offset in seconds, not minutes.
	(lisp_time_argument, difftm): New functions.
	(Fcurrent_time_string): Use lisp_time_argument.
	* systime.h (EMACS_CURRENT_TIME_ZONE, EMACS_GET_TZ_OFFSET,
	EMACS_GET_TZ_NAMES): Remove.
	* config.h.in: Add HAVE_TM_ZONE.

	proper combination of <time.h> and <sys/time.h>.

	combination of <time.h> and <sys/time.h>.

	(EMACS_SET_USECS): Remember that a `usec' is a microsecond, not a
	millisecond.  What's three orders of magnitude between friends?
	* dispnew.c (Fsit_for, Fsleep_for): Remember to multiply the
	`milliseconds' argument by 1000 to get microseconds.

	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.

	#defined.

	* [VMS] systime.h: Include vmstime.h.  VMS has the timezone
	variable and the tzname array.
	* s/vms.h: VMS does have select.
	mth$dmod is the same as Unix's drem.
	Use the time functions in vmstime.c.
	No need to rename the malloc routines if we're using GNU malloc.
	PURESIZE needs to be 330000.
	* vmstime.c, vmstime.h: New files.
	* systty.h: Don't try to initialize extern declarations under VAX C.
	* vmspaths.h (PATH_LOADSEARCH): Include EMACS_LIBRARY:[LOCAL-LISP]
	in PATH_LOADSEARCH.
	(PATH_EXEC): Use EMACS_LIBRARY:[LIB-SRC] instead of [ETC].
	* sysdep.c [VMS] (init_sys_modes): Don't allocate process_ef.
	[VMS] (queue_kbd_input): Build events structure correctly.
	[VMS] (gethostname): New function.
	[VMS] (getwd): Don't get the PATH environment variable; that's
	dumb.  Call getcwd.

	variable under USG 5-4.

	(EMACS_GET_TZ_OFFSET) [USG]: Don't declare twice.  Prefer tzset.

	(offset).  Don't forget the while corresponding to the do.
	Include USG in the list of systems that have a tzname array.
