[section:make_signed make_signed]

   template <class T>
   struct make_signed
   {
      typedef __below type;
   };
   
   template <class T> using make_signed_t = typename make_signed<T>::type; // C++11 and above

__type If T is a signed integer type then the same type as T, if T is an 
unsigned integer type then the corresponding signed type.  
Otherwise if T is an enumerated or
character type (char or wchar_t) then a signed integer type with the same
width as T.

If T has any cv-qualifiers then these are also present on the result type.

[*Requires:]  T must be an integer or enumerated type, and must not be the type
bool.

__std_ref 3.9.1.
