 `wp_load_translations_early()` includes `functions.php`, which in turn
 includes `option.php`. This leads to the parse error when running PHP 4
 (due to the `clone` keyword being used there):
 {{{
 Parse error: syntax error, unexpected T_VARIABLE in wp-includes/option.php
 on line 225
 }}}
 http://core.trac.wordpress.org/browser/tags/3.4.1/wp-
 includes/option.php#L224

 In 3.3, a proper error message was shown:
 {{{
 Your server is running PHP version 4.4.7 but WordPress 3.3.3 requires at
 least 5.2.4.
 }}}
