Update.
2003-06-17 Thorsten Kukuk <kukuk@suse.de> * nis/Makefile: Remove NIS/NIS+ files from nss_compat module. * nis/nss_compat/compat-grp.c: Don't use our own NIS/NIS+ functions, dlopen corresponding NSS module instead. * nis/nss_compat/compat-pwd.c: Likewise. * nis/nss_compat/compat-spwd.c: Likewise. * nis/nss_compat/compat-initgroups.c: Disabled for now. * nss/Versions: Export __nss_lookup_function. 2003-06-19 Daniel Jacobowitz <drow@mvista.com> * sysdeps/unix/sysv/linux/kernel-features.h: Update kernel features for the SH architecture. 2003-06-25 Thorsten Kukuk <kukuk@suse.de> * csu/Makefile: Use CPPFLAGS to find correct linux/version.h.
