  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
