Some time ago I posted a mail to grassu-list describing
my problems with r.slope.aspect. In particular, the old
version produced distinct peaks at the cardinal aspects
(just as Ron Thomas describes) which could not be entirely
due to the particular DEM used. The new (current) version
simply bombed on the same data, so I never got to 
find out if it produced the same peaks. Is there anybody
going to delve into this? If the aspect calculation cannot
be trusted I cannot use it in any analyses....
