Extended Description

The C++11 standard defines pointer_safety as:
enum class pointer_safety { relaxed, preferred, strict };

But, currently pointer_safety is implemented as a struct.

This causes that the following test to fail, because it is initialized by a constructor that takes an int:

#include

int main()
{
std::pointer_safety d ;
d = std::get_pointer_safety();

return 0;

}

test.cpp:5:25: error: no matching constructor for initialization of 'std::pointer_safety'
std::pointer_safety d ;
