Porting Message:  Due to differences between implementations of the

      exectuion.  Either enable one of the LEX_YACC sets above on this
      architecture or add an additional set of macros to save/restore
      the variables used by lex and yacc.  This is done via inspection
      of the generated lex/yacc output files for any non-automatic
      state variables.  You might also need to make additions to the
      file acf.h depending on your implementation of lex/yacc.  See
      the comments in acf.h for more information.
