Hi Uwe,
I'm sorry about the delay replying to this message. I've investigated
your problem and its another of those "Hmmm, why doesn't this break
all the time things". I'll check a fix into the CVS sources.
In the meantime I have two possible work arounds:
The first is to change the definition of StateTrans in StateTrans.hs
from a newtype to a datatype. Unfortunatley this may distort your
profiles, so .....
The second is a hack, you'd better email me if you want it.
Incidentally, you will need to add the -prof option to the linking
phases of pplc and testNtree in the Makefile.
regards
Kevin
