* sysdeps/generic/errno.c (__libc_errno): Remove alias. * inet/herrno.c (__libc_h_errno): Likewise. * resolv/res_libc.c (__libc_res): Likewise. [USE___THREAD]: Use this in place of [USE_TLS && HAVE___THREAD]. (__res_state) [! USE___THREAD]: Don't define as weak. * csu/Versions: Revert last change. * resolv/Versions: Revert last change.
