Why zend_language_scanner_cc.cc instead of zend_language_scanner.c?

Trying to debug a SEGFAULT on AIX and I think it is related to the fact that my configuration is compiling zend_language_scanner_cc.cc rather than zend_language_scanner.c. How can I make zend_language_scanner.c be compiled instead of zend_language_scanner_cc.cc? I think you can safely ignore the 'warning' messages.
