      3: !  Part of the base include file for Fortran use of PETSc.
      4: !  Note: This file should contain only define statements and
      5: !  not the declaration of variables.

      7: ! No spaces for #defines as some compilers (PGI) also adds
      8: ! those additional spaces during preprocessing - bad for fixed format
