1 8.14.1 Preprocessing Fortran 77
1 -------------------------------

1 ‘N.f’ is made automatically from ‘N.F’ or ‘N.r’.  This rule runs just
1 the preprocessor to convert a preprocessable Fortran 77 or Ratfor source
1 file into a strict Fortran 77 source file.  The precise command used is
1 as follows:
1 
1 ‘.F’
1      ‘$(F77) -F $(DEFS) $(INCLUDES) $(AM_CPPFLAGS) $(CPPFLAGS)
1      $(AM_FFLAGS) $(FFLAGS)’
1 
1 ‘.r’
1      ‘$(F77) -F $(AM_FFLAGS) $(FFLAGS) $(AM_RFLAGS) $(RFLAGS)’
