* sunrpc/rpc_thread.c: Likewise for text_set_element use. (__rpc_thread_destroy): Add it to __libc_subfreeres too. * include/resolv.h: Add libc_hidden_proto for __res_nclose. * resolv/res_init.c (__res_nclose): Add libc_hidden_def. (res_thread_freeres): New function, on __libc_thread_subfreeres and __libc_subfreeres. * malloc/Versions (libc: GLIBC_PRIVATE): Add __libc_thread_freeres. * sunrpc/Versions (libc: GLIBC_PRIVATE): Removed.
