From 5a3ec90c8165b94111cbdac75032f208e7b20cf6 Mon Sep 17 00:00:00 2001
From: Jim Meyering <jim@meyering.net>
Date: Mon, 2 Jul 2001 07:39:33 +0000
Subject: (Makefile.am): Include jm-glibc-io.m4n in emitted definition of
 EXTRA_DIST. (Makefile.am): Emit the dependency, `all-local: jm-glibc-io.m4'
 to ensure that the generated file is created/updated whenever the list of
 $(unlocked_functions) is changed. (jm-glibc-io.m4): New rule.
 (unlocked-io.h): New rule -- currently unused.
