I think the latter. I think one can allow all intrinsic types. However, one needs to be careful with characters: kind=4 is not interoperable and, e.g., for dummies only len=1 is allowed (while via storage association, c_char_"string" is a valid argument for a "character(len=1,kind=c_char) :: dummy(*)"). Note, additionally, that setting attr.is_c_interop is kind of difficult for 0.0_c_int ...
