The argument list for PetscOptionsGetInt() changed in this release (so we

additional argument at the beginning. I am guessing there is a mismatch
here between the version from which ex1.c comes
and the version you are linking.

What most experimenters take for granted before they begin their
experiments is infinitely more interesting than any results to which their
experiments lead.
