Don't cast pointers to int, but to unsigned long for the health of 64-bit systems. * sunrpc/svc_udp.c: Define MAX only if we don't have it yet. Many system's <sys/param.h> pulls this in. * sysdeps/generic/dl-cache.c: Kill the bottom half of the patch doubled file. * sysdeps/generic/pty.c (forkpty): Get login_tty decl from <utmp.h> instead of defining it locally. * sysdeps/posix/sigvec.c: Prototype wrapper_handler and convert_mask. * sysdeps/stub/chflags.c: Prototype chflags. * sysdeps/stub/fchflags.c: Prototype fchflags. * sysdeps/stub/sstk.c: Prototype sstk. * sysdeps/unix/alpha/sysdep.S: Add strong alias from errno variable to __errno.

(nss_parse_service_list): Initialize action for NSS_STATUS_RETURN to NSS_ACTION_RETURN. * nss/nss_db/db-netgrp.c: New file. * nss/nss_files/files-netgrp.c: New file. * nss/nsswitch.conf: Add entry for netgroup. * resolv/netdb.h: Add prototypes for netgroup functions. * nss/nss_db/db-XXX.c: Use `enum nss_status' type when status value is used. Sun Sep 29 12:55:58 1996 Ulrich Drepper <drepper@cygnus.com> * sysdeps/unix/sysv/linux/syscalls.list: Change funciton name for _llseek to _llseek (not llseek). Reported by Matthias Urlichs <smurf@smurf.noris.de>. Sun Sep 29 05:34:32 1996 Ulrich Drepper <drepper@cygnus.com> * inet/rcmd.c: Remove definition of MIN.
