/* This is just a compilation test, to see if we have a version of OpenSSL with
   NPN support installed. It's not meant to be run, and all of the values and
   function calls there are non-sensical. The code is only meant to test the
   presence of symbols, and we're expecting a compilation failure otherwise. */
