Browse source 
This fixes a bug in the powerset of such TGBA on the minimize branch.

* src/tgba/tgbabddconcrete.cc (compute_support_conditions): Also
account for the conditions from the acceptance relations.
* rc/tgba/tgbabddconcretefactory.hh, rc/tgba/tgbabddconcretefactory.cc
(acceptance_conditions_support): New variable to hold the value
of bdd_support(acceptance_conditions_support).
* src/tgba/tgbabddconcretefactory.cc (finish): Update
