+Subject: [PATCH] Fix build with LibreSSL
+
+OPENSSL_VERSION_NUMBER is used to test the version of OpenSSL but this
+test alone breaks the build with LibreSSL due to implicit declarations
+of functions 'RSA_set0_key' and 'HMAC_CTX_free'.
+
+Test if OpenSSL < 1.1.0 or LIBRESSL_VERSION_NUMBER is defined, instead.
