Thanks this is working a treat;

>>Martin, I suspect your option would work as well, but its nice to keep it
purely in ANT until I *have* to get more complex :).


  <target name="look.for.conflict">        
    <fileset dir="${conflict.dir}" includes="**/*.*" id="conflict.files" >
      <present targetdir="${patch.dir}/${cvspackage}/${patch.name}"/>
    </fileset>
    <pathconvert targetos="unix" pathsep="" property="conflict.files"
refid="conflict.files" />
    <echo  message="conflict.files:${conflict.files}" level="info"/>
    <condition property="conflict.files.exist">
      <not>
	  <or>
	    <equals arg1="${conflict.files}" arg2=""/>
	  </or>
      </not>
    </condition>    
  </target>
