Parse error on adminlib.php

The moodle_19_weekly build 20080730 seems affected by teh following parse error when running on php4:

Parse error: syntax error, unexpected T_STRING, expecting T_OLD_FUNCTION or T_FUNCTION or T_VAR or '}' in /path/to/moodle/lib/adminlib.php on line 3517

In PHP 5 the error does not appear. This issue makes impossible to update sites to weekly build on PHP4 servers.
