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.
