	* 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.

and with GNU autoconf 2.52 patched as follows:

2001-09-15  Paul Eggert  <[email protected]>

	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.
