There are list archives from that time, here:
<http://sourceware.org/ml/autoconf-patches/2000-06/msg00083.html>

I have had collecting and sending them to gmane.org for inclusion on my
"todo sometime" list forever.  If somebody wants to do it, I'd be
delighted.  (gmane has a nice strategy to insert old content while
keeping ordering and link stability; see <http://gmane.org/import.php>.)

Too tired ATM, sorry.  At first glance, it looks scary, changing quite
fundamental aspects of AC_REQUIRE.
