+Subject: [PATCH] Fix building against LibreSSL
+
+LibreSSL declares OPENSSL_VERSION_NUMBER == 2.0 but does not include most
+changes from OpenSSL >= 1.1.
+
+To work around this:
+
+- Check to see if LIBRESSL_VERSION_NUMBER is defined.
+- If so, define MODSSL_USE_OPENSSL_PRE_1_1_API.
+- Change all checks for OPENSSL_VERSION_NUMBER < 0x10100000L to
+  '#if MODSSL_USE_OPENSSL_PRE_1_1_API'
+
+Upstream-Status: Committed
