1998-07-17  Martin Baulig  <baulig@Stud.Informatik.uni-trier.de>

	* sysdeps/sun4/proclist.c (glibtop_get_proclist_p): Added
	implementation of that feature.

	* sysdeps/sun4/proc_{uid,state}.c: Now working quite well.

	* sysdeps/sun4/proc_{mem,time,signal,kernel,segment}.c: Added
	some basic implementation; this isn't really working yet.
