 - Z3 by default switches to an incremental solver when a Solver object is used to solve many queries.
   In the this version, we switch back to the tactic framework if the incremental solver returns "unknown".
 
+- Now, Z3 can be compiled inside cygwin using gcc.

+- Fixed bug in the unsat core generation.
