Update.
2002-11-20 Ulrich Drepper <drepper@redhat.com> * inet/getnameinfo.c: Use extend_alloca where appropriate. * sysdeps/posix/getaddrinfo.c: Likewise. * include/alloca.h (extend_alloca): New define. Based on stack direction it'll try to append to the previouls allocated buffer. 2002-11-07 Thorsten Kukuk <kukuk@suse.de> * sysdeps/posix/getaddrinfo.c (gaih_inet): If AF_UNSPEC is set, use the same service for AF_INET and AF_INET6. 2002-11-19 Ulrich Drepper <drepper@redhat.com> * intl/localealias.c (read_alias_file): Use only about 400 bytes of stack space instead of 16k.
