+Subject: [PATCH] OpenSSL improvements
+
+- Fix build issues with OpenSSL 1.1 (OpenSSL 1.1 and later no longer
+  provides CRYPTO_set_locking_callback(), since locking is now performed
+  internally.)
+- Detect whether the platform has /dev/urandom at compile time, rather
+  than assuming that all Sun and SGI machines don't have it (Solaris 10
+  and later supports /dev/urandom.)
