+
+The change of implementation of AC_REQUIRE in 2.64 caused a regression
+in the arts project.
+This can be fixed by shuffling some macro calls.
+
+I suppose that most of this patch will not be needed with a future
+release of Autoconf.
+But the last chunk of this patch is a real bug in this source and
+should go upstream.
