+Subject: [PATCH 54/79] Fix binary incompatibility between openssl versions
+
+OpenSSL changed the layout of X509_STORE_CTX between 0.9 and 1.0
+So we have to consider this struct as private implementation, and use
+the access functions instead.
+
+This bug would cause certificate verification problems if a different
+version of openssl is loaded at runtime to the headers Qt was compiled
+against.
+
+Task-number: QTBUG-28343
+Change-Id: I47fc24336f7d9c80f08f9c8ba6debc51a5591258
+Reviewed-by: Richard J. Moore <rich at kde.org>
