For a more direct version, do this:

IntVar i(home, Limits::Int::int_min(), Limits::Int::int_max()); // 
creates a -inf,+inf single range
GC_StlSetRangeIterator it(&s);
IntView iv(i); // modifiable wrapper  around Int var implementation
GECODE_ME_FAIL(home, iv.inter(it)); //modify upper bound of var by 
intersecting its ranges with the set iterator
cout << i << endl;

This way, you don't need to create the intermediate IntSet (and the 
intermediate vector as I did because I forgot the std::set was already 
sorted).

Best,
