std::ios_base::io_state not an integer type

depr.ios.members, p2 requires that std::ios_base::io_state be an integer type. The program below fails to compile, indicating that in stdcxx it is not:

$ cat t.cpp && make t
#include <ios>

int main ()
{
const int i = 1;
std::ios_base::io_state s = i;
}
