FWIW, the Clang counterpart to this bug is

--- Comment #9 from Jiang An <de34 at live dot cn> ---
Additionally, what happens when I write `using my_size_t =
decltype(sizeof(0));` (C++) or `typedef typeof(sizeof(0)) my_size_t;` (GNU C or
C23)?
I think such enhancement of warnings effectively requires size_t to be some
kind of "strong typedef", and the "strength" should be generated from sizeof,
alignof, etc..
Perhaps the built-in operator- between pointers also needs to generate such
"strength" for the purpose of ptrdiff_t.
