--- Comment #1 from Marek Polacek <mpolacek at gcc dot gnu.org> ---
GCC is correct here, and this behavior is intentional:

  /* Applying the _Atomic qualifier to an array type (through the use
     of typedefs or typeof) must be detected here.  If the qualifier
     is introduced later, any appearance of applying it to an array is
     actually applying it to an element of that array.  */
  if (atomicp && TREE_CODE (type) == ARRAY_TYPE)
    error_at (loc, "%<_Atomic%>-qualified array type");
