intel has it in 11.1 (maybe in 10.1 too). PGI says it has it too, but I was not able to compile my silly example with the antyique 7.1 installed on ranger

Everybody that uses a compiler that supports it. they may not take advantage of it, but the fortran 2003 functionalities should be available.
Another goodie is interoperability of C structs and fortran derived types.

Back to enum, I was hoping that direct translations between C and fortran enum would make it possible to write PetscOptionsGetENum and PetscBagRegisterEnum fortran bindings.
