[petsc-users] compilation error with latest petsc source

[Vanella, Marcos (Fed) via petsc-users]

Hi, I did an update and compiled PETSc in Frontier with gnu compilers. When 
compiling my code with PETSc I see this new error pop up:

It seems the use of PETSC_NULL_INTEGER is causing an issue now. From the PETSc 
docs this entry is nnz which can be an array or NULL. Has there been any change 
on the API for this routine?

Thanks,
Marcos

PS: I see some other erros in calls to PETSc routines, same type.
