+This release was built with GNU automake 1.5 patched as follows:
+
+2001-09-24  Paul Eggert  <eggert@twinsun.com>
+
+	* m4/header.m4 (_AM_Config_Header_Index): Remove.
+	(AM_CONFIG_HEADER): Don't use it.  It wasn't working, and was
+	causing needless rebuilds.
+
+2001-09-14  Paul Eggert  <eggert@twinsun.com>
+
+	* lib/am/distdir.am (REMOVE_DISTDIR):
+	New macro.  Do not change permission of non-directories.
+	(distdir, dist, dist-bzip2, dist-tarZ, dist-shar, dist-zip, dist-all,
+	 distcheck): Use it.

+
+2001-09-15  Paul Eggert  <eggert@twinsun.com>
+
+	Fix bug reported by Paul Townsend on AIX 4.3.3.0 with
+	CFLAGS=-O4 or CFLAGS=-O5.  In that case, the linker has a
+	relaxed view of fatal errors, and AC_CHECK_LIB causes it to
+	include libraries even when they don't exist.
+
+	* acheaders.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS, not
+	AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
+	need it.
+
+	* acspecific.m4 (AC_ISC_POSIX): Replace the old, crufty
+	version with the version used by fileutils 4.1, except use
+	AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use
+	-lcposix if we don't need it.
