From: Paul Eggert <eggert@cs.ucla.edu>
Date: Tue, 30 Nov 2004 21:41:09 +0000
Subject: (USER_PROCESS, RUN_LVL, INIT_PROCESS, LOGIN_PROCESS, DEAD_PROCESS,
 BOOT_TIME, NEW_TIME, UT_TYPE_UNDEF, UT_TYPE): Remove. (IS_USER_PROCESS): Move
 to ../lib/readutmp.h. (UT_TYPE_RUN_LVL, UT_TYPE_INIT_PROCESS,
 UT_TYPE_LOGIN_PROCESS, UT_TYPE_DEAD_PROCESS, UT_TYPE_NEW_TIME): New macros.
 (gethostname): Remove decl. (list_entries_who, scan_entries): Use the new
 macros defined above, for consistency with pinky, uptime, and users.
