+Fix things so that chains of certificates work in the server and client
+certificate files.
+
+This only really works for OpenSSL-based builds, as yassl is unable to read
+multiple certificates from a file.  The patch below to yassl/src/ssl.cpp
+doesn't fix that, but just arranges that the viosslfactories.c patch won't
+have any ill effects in a yassl build.  Since we don't use yassl in Red Hat/
+Fedora builds, I'm not feeling motivated to try to fix yassl for this.
+
+See RH bug #598656.  Filed upstream at http://bugs.mysql.com/bug.php?id=54158
