[patch] testsuite file fails concept-checks

This patch is fine, but your spacing is off. 

-      _Tp __c(__a) _IsUnused;           // require const copy constructor
+      _Tp __c _IsUnused (__a);           // require const copy constructor

should be

+      _Tp __c _IsUnused(__a);           // require const copy constructor

And others. With this issue fixed this is ok for 3.4 and mainline.

Thanks,
benjamin
