scons: building terminated because of errors.

Compilation started with the following statement...

$ scons --ssl --disable-warnings-as-errors --prefix=/usr core install

Error corrected by modifying struct TLSVersionCounts in file src/mongo/util/net/ssl_manager.h by inserting new line 111 with text...

AtomicInt64 tls13;

This error was encountered in system running Slackware (Linux) x86_64 Current with OpenSSL 1.1.1 and 1.0.20 installed.

No patch file provided. Again, this was encountered and tested in version 3.6.8. Not sure if this applies to any other (newer, major version) releases.
