I am not surprised.  The DC part is ok.  I had a lot of trouble 
with the dynamic part.  This experience was a big factor in 
convincing me that the model strategy needed to change.  I 
don't want to port models.  Gnucap needs to be able to use 
models developed by others with no changes.

In the future there will be no built-in models.  That's what 
plugins are for.
