+Subject: [PATCH] crypt_openssl_mgt: define DISABLE_ENGINES after
+ OPENSSL_NO_ENGINE
+
+With LibreSSL-3.8.1 these engines are no long available causing a build
+failure, but LibreSSL correctly defines OPENSSL_NO_ENGINE as part of its
+opensslfeatures.h. However Tor includes crypto_openssl_mgt.h before any
+of the openssl includes which would define OPENSSL_NO_ENGINE and then
+fails to define DISABLE_ENGINES.
+
+As the define is used in only a single .c file it is best to move it
+there.
