Some VMS changes from Richard Levitte <levitte@e.kth.se>:

	* [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.
