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.
