Description:
------------
A git checkout of PHP-5.4 no longer builds with versions of bison before 2.4 due to the use of %code requires.

The specific errors:

/home/aharvey/trees/php-src/5.4/Zend/zend_language_parser.y:50.1-5: invalid directive: `%code'
/home/aharvey/trees/php-src/5.4/Zend/zend_language_parser.y:50.7-14: syntax error, unexpected identifier

This came about in the fix for bug #64503: https://github.com/php/php-src/commit/a4862503d485abf449e0565ac03157d859a31bf7

Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to report
a bug at http://bugs.php.net/how-to-report.php

Since 5.4 is closed to non-security fixes, this probably won't be fixed, so the alternative is to upgrade bison.
