2001-10-26 Ulrich Drepper <drepper@redhat.com> * string/strxfrm.c [USE_IN_EXTENDED_LOCALE_MODEL]: Correctly get nrules value. 2001-10-24 H.J. Lu <hjl@gnu.org> * sysdeps/generic/bits/dlfcn.h (DL_CALL_FCT): Cast to void *. Use __BEGIN_DECLS/__END_DECLS around prototypes. * sysdeps/mips/bits/dlfcn.h (DL_CALL_FCT): Likewise. 2001-10-21 Jim Meyering <meyering@lucent.com> * malloc/obstack.c (_): Honor the setting of ENABLE_NLS. Otherwise, this code would end up calling gettext even in packages built with --disable-nls. * posix/getopt.c (_): Likewise. * posix/regex.c (_): Likewise. 2001-10-26 Ulrich Drepper <drepper@redhat.com> * resolv/gethnamaddr.c (gethostbyaddr): Use ip6.addr for reverse lookup not ip6.int. * resolv/nss_dns/dns-host.c (_nss_dns_gethostbyaddr_r): Likewise. Reported by Martin.v.Loewis@t-online.de [PR libc/2598]. 2001-10-19 Jakub Jelinek <jakub@redhat.com> * misc/sys/cdefs.h (__attribute_used__): Define. * elf/rtld.c (_dl_start): Add __attribute_used__. * elf/dl-runtime.c (fixup, profile_fixup): Likewise.
