- Fortran 90 supported all fortran77 features, but designated a few features as obsolete, such as arithmetic if, real and double precision DO variables, shared do termination, H edit descriptor, computed GOTO.
- fortran95 deleted the fortran90 obsolete features. 

As far as I know, there are no additions to the obsolete / deleted lists

I am not suggesting that the whole fortran binding system be rewritten at this point, but it would be nice to have access to enum from PetscBag and PetscOptions using the compilers that support it (and I wouldn't be surprised if they all do. I am willing to check).
