c6b0fc444c Fix VisualStudio 2010 compiler warning C4100 
When compiling with Visual Studio 2010 the buildlog warns of the following: `z3++.h: warning C4100: 'e' : unreferenced formal parameter` and `z3++.h: warning C4100: 'c' : unreferenced formal parameter`. This merge request removes this warning.

481e97a274 propagate early in theory_str to set up contains/regex maps 
this fixes an unsat-as-sat error in a regex test and flips around some timeouts
so more work will be required to track this down
