B is correct. We don't care about function pointers because we know if a static function has its address takes in the same compilation unit in which it appears. If it has not had its address taken, we don't have to care about the system ABI. If it has, then we need to use the system ABI. -- Andrew Haley Java Platform Lead Engineer Red Hat UK Ltd. <https://www.redhat.com> EAC8 43EB D3EF DB98 CC77 2FAD A5CD 6035 332F A671
