[petsc-dev] MUMPS and 64 bit indices

It's possible to configure PETSc with the options

    --with-64-bit-indices --download-mumps

and compile and run, but it doesn't look like the MUMPS interface 
supports 64 bit indices. Should the above combination throw an error at 
configure time?

(On a side note, SuperLU_dist and Umfpack are flaky with 64 bit 
indices, which seems largely related to calling ParMETIS/METIS).
