  Matt needs to add something like

     PetscSection, parameter :: PETSC_NULL_SECTION = tPetscSection(-1)
     PetscSectionSym, parameter :: PETSC_NULL_SECTIONSYM = tPetscSectionSym(-1)

to src/vec/f90-mod/petscis.h in the master branch.

Long ago, in the past, I've used to set the section input parameters to PETSC_NULL_OBJECT. That now returns an error -- no implicit type -- during compilation. Looking at the defined null objects for fortran I don't see a section option. What should I use to invoke the default sections?
