Doh, that'll teach me to run off a reply with concentrating.

In that case how about setting a property who name is based on the value of
another property.

eg <property name="Is.${os.name}" value="true"/>

where os.name property you are interested in.

You can then use if/unless testing if, for example, Is.Solaris is defined.

... and then come back and say, "No, that doesn't actually do what I
asked."

if/unless specify whether or not to execute a task if a property is set
*at all*, not if a property has a specific value.
