Hello, attached patch fixes build with OPENSSL_NO_NEXTPROTONEG. While it cannot be enabled via ./config options, compiling OpenSSL with this define turned out to be extremely useful while adding ALPN support to 3rd-party software (i.e. to make sure that nothing in the added ALPN support relies on NPN code).
Also, I wanted to make sure that SSL_select_next_proto() is not part of NPN and that it will be available going forward. Best regards, Piotr Sikora
