My point is that libstdc++ does not use a using declaration for
std::size_t, in c++config.h there is:

namespace std
{
  typedef __SIZE_TYPE__     size_t;

This means std::size_t is a synonym for the same underlying type as
size_t, but in a separate tree.

OK.  Sorry I don't know the answer to your question.
