Stop.

Stop.

You have ported the output of yacc/bison (field_y.c) rather than porting the yacc source (field_y.y?) that generated this C source. If you will instead run the yacc/bison source through the HP-UX version of yacc/bison to generate an HP-UX version of field_y.c, I think your problems will disappear.
