[petsc-dev] GCC8 Fortran length changes from int to size_t

[Smith, Barry F.]

   Jeff, (and others),

     Do you know of a tool that can take a C prototype and automatically generate the Fortran C binding interface definition? We currently generate stubs for C functions that have character arguments manually and it would be great to remove that manual step.

   Thanks

      Barry
