Check out the AntContrib tasks at <http://ant-contrib.sourceforge.net/ tasks/tasks/index.html>. There is actually an <if> ant task at <http://ant- contrib.sourceforge.net/tasks/tasks/if.html>. I've used it quite successfully with Ant 1.7.

If you don't want to use optional tasks, you can use the <condition> task like this to emulate an <if><else> task:

<condition
    property="os_is_windows"
    value="true">
    <os family="windows"/>
</condition>
<antcall task="windows_task"/>
<antcall task="unix_task"/>

<task name="windows_task if="os_is_windows">
    <blah>
    </blah>
</task>

<task name="unix_task" unless="os_is_windows">
    <blah>
    </blah>
</task>
