Hi, can one of the C gurus have a look at this? http://thread.gmane.org/gmane.comp.gis.grass.devel/15495/focus=15598 I think it's a simple type mismatch in variables getting passed to a function. I'd like to have r.le.* all working for 6.2.0 as it will probably be the final time r.le.* is released. thanks, Hamish
