Update.
1998-08-21 17:21  Ulrich Drepper  <drepper@cygnus.com>

	* sysdeps/unix/sysv/linux/glob64.c: Define __stat using __xstat64.

1998-08-20  Andreas Schwab  <schwab@issan.informatik.uni-dortmund.de>

	* Makefile (elf/ldso_install): Put back.  The problem still persists.
	* elf/Makefile (ldso_install): Likewise.

1998-08-20  Andreas Schwab  <schwab@issan.informatik.uni-dortmund.de>

	* db2/db/db.c (db_open) [_LIBC]: Rename to __nss_db_open and
	create weak alias.
	* include/db.h: Declare __nss_db_open.
	* db2/Versions: Export it.

	* db2/makedb.c: Convert to use db2 API.
	* nss/nss_db/db-XXX.c: Likewise.
	* nss/nss_db/db-netgrp.c: Likewise.
	* nss/nss_db/db-alias.c: Likewise.
	(_nss_db_getaliasent_r): Allow retrying with a larger buffer.

1998-08-19  Andreas Schwab  <schwab@issan.informatik.uni-dortmund.de>

	* sysdeps/unix/sysv/linux/Makefile (sysdep_routines): Remove
	sys_setresuid, already built automatically (or not).
	* sysdeps/unix/sysv/linux/syscalls.list: Define __setresuid
	instead of __syscall_setresuid and add back setresuid.
	* sysdeps/unix/sysv/linux/seteuid.c: Use __setresuid instead of
	__syscall_setresuid.

1998-08-21  Andreas Jaeger  <aj@arthur.rhein-neckar.de>

	* sysdeps/unix/sysv/linux/sys/mount.h: Fix typo.

	* libio/libioP.c (FILEBUF_LITERAL): Also initialize new _offset
