Well, f you can prove this for armhf and/or armel, we can certainly do it. -- 7: Hay diferencia entre "cortar" un archivo y "borrarlo" o "eliminarlo" * Depende cuando se "cuelgue" Windows Damian Nadales http://mx.grulic.org.ar/lurker/message/20080307.141449.a70fb2fc.es.html Lisandro Damián Nicanor Pérez Meyer http://perezmeyer.com.ar/ http://perezmeyer.blogspot.com/
