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

16: ! PETSc double/complex variables are not affected by
17: ! compiler options like -r4,-r8, sometimes invoked
18: ! by the user. NAG compiler does not like integer*4,real*8
