Update.
2003-07-22 Jakub Jelinek <jakub@redhat.com>
* include/resolv.h (__resp): Declare. Define to __libc_resp
if in libc.so.
(_res): If USE___THREAD, define to (*__resp).
* resolv/res_libc.c (_res): Normal .bss variable with compat_symbol
even if USE___THREAD.
(__resp): New __thread variable.
(__libc_resp): New alias.
* resolv/Versions (libc): Export _res@GLIBC_2.0 even if
USE_TLS && HAVE___THREAD. Export __resp@@GLIBC_PRIVATE.
* sysdeps/generic/res-state.c (__res_state): Return __resp
if USE___THREAD.
