From ba404b5e86a707afe7faca8e22d53eea5e64c8b6 Mon Sep 17 00:00:00 2001
From: "Dr. Stephen Henson" <steve@openssl.org>
Date: Sun, 20 Jun 1999 22:18:16 +0000
Subject: Convert the CONF library to use a typesafe stack: a
 STACK_OF(CONF_VALUE). It seemed like a good idea at the time... several hours
 later it was rather obvious that these are used all over the place making the
 changes rather extensive.
