Update.

2003-09-01  Thorsten Kukuk  <kukuk@suse.de>

	* nis/nss_compat/compat-spwd.c (getspnam_plususer): Return
	NSS_STATUS_SUCCESS if entry was found.
	(getspent_next_file): Store user in blacklist after entry
	was found, use innetgr.

2003-09-01  Jakub Jelinek  <jakub@redhat.com>

	* sysdeps/unix/sysv/linux/powerpc/powerpc32/posix_fadvise.c: New.
	* sysdeps/unix/sysv/linux/powerpc/powerpc32/posix_fadvise64.c: New.

	* sysdeps/generic/dl-tls.c (_dl_determine_tlsoffset): Fix tls offset
	computation for TCB_AT_TP.  Support l_firstbyte_offset != 0 for
	DTV_AT_TP, optimize.
