PETSc Fortran interfaces are a combination of automatically generated and manually generated.
For any C PETSc function if the manual page begins with /*@ it generates the Fortran interface automatically (make allfortranstubs). If it begins /*@C then either the Fortran interface is done manually or is missing. C functions that have character string arguments or function arguments (or a few other special cases) need to be manually provided. The automatically generated stubs go in the directory ftn-auto while manually generated ones go in the directory fin-custom. Perhaps you could first generate a list of "missing" Fortran stubs and then for each stub determine why it is missing and if it can be provided. Some are likely easy to provide but a few (involving function arguments) will be more involved. Once you have all the stubs available translating ex11.c becomes straightforward.
