Assuming both are restricted to BIND(C) interfaces only, an important 
difference, in my mind, is that #3 above only addresses TK mismatch. Rank 
mismatch, strided arrays, dope vectors, and anything other than type is 
covered by existing Fortran rules, whether they be good or bad. It is exactly 
as it is for CLASS(*) dummy arguments in Fortran 2003, the only difference is 
that no type descriptor would be passed to C, only an address.
