- * This macro pastes a specialization of builtin_add_overflow using MSVC's
- * U(Int/Long/LongLong)Add.
- *
- * The add function is implemented by forwarding the parameters to the
- * intrinsic. As MSVC's intrinsics return S_OK on success, this specialization
- * returns whether the intrinsics return value does not equal S_OK. This ensures
- * a uniform interface of the add function (false is returned when no overflow
- * occurs, true on overflow).
- *
- * The intrinsics are documented here:
- * https://msdn.microsoft.com/en-us/library/windows/desktop/ff516460(v=vs.85).aspx
