Very old. There has been a lot of changes to the JFFS2 support since
then. So your millage may vary.

Support for this was added 2003/12/02 14:40:19. eCos 2.0 was released
sometime around 2003/02/14. So this is obviously not going to work.
Put your eCos sources in a museum and try again with something more
uptodate.
