Changes for correct pgrp behavior; approach suggested by Bob

	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.

	* config.h.in (HAVE_CLOSEDIR): Add an #undef for autoconf to
	change.
	* sysdep.c (closedir): Only define this if autoconf can't find
	HAVE_CLOSEDIR.  If we're running under solaris (defined (sun) &&
	defined (USG5_4)), then don't free the buffer separately.
