You can put the os.name property (or any other Ant built-in or user-defined
property) in a property file using the <propertyfile> task.   Here's how I
do it:

    <propertyfile comment="Build Information"
file="${build.dir}/classes/version.properties">
        <entry key="version" value="${version}"/>
        <entry key="build.date" pattern="EEEE MMM dd, yyyy" type="date"
value="now"/>
        <entry key="build.time" pattern="kk:mm:ss" type="date" value="now"/>
        <entry key="build.host" value="${env.COMPUTERNAME}"/>
        <entry key="build.user.name" value="${user.name}"/>
        <entry key="build.os.name" value="${os.name}"/>
        <entry key="cvs.tag" value="${cvs.tag}"/>
    </propertyfile>

Yes, it would take a couple of steps to auto-increment a number in a
properties file, then load that properties file to get its value for use in
file naming.
