Update.
2004-06-05 Ulrich Drepper <drepper@redhat.com> * stdio-common/_itoa.h: Don't expand _itoa inline for libc. * stdio-common/_itoa.c: Add _itoa implementation. * nscd/nscd_gethst_r.c (__nscd_open_socket): Change implementation to also send request. Add parameter to allow this. Change callers. * nscd/nscd_getgr_r.c: Change __nscd_open_socket caller. * nscd/nscd_getpw_r.c: Likewise. * nscd/nscd-client.h: Change __nscd_open_socket prototype.
