+
+	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.
