+ * testsuite/20_util/unique_ptr/cons/cv_qual.cc: Move negative tests
+ to new file.
+ * testsuite/20_util/unique_ptr/cons/cv_qual_neg.cc: New file. Fix
+ test for incompatible deleters to not also use incompatible types.
+ Add tests for incompatible array types.
+
* include/experimental/bits/shared_ptr.h
(__shared_ptr<__libfund_v1<_Tp, false>, _Lp>::_Compatible): Just use
is_convertible for non-array specialization.
