* src/reader.c (reader): Remove call to free_symtab ().
* src/main.c (main): Call it here. Include symtab.h. * src/conflicts.c (initialize_conflicts): Rename as... (solve_conflicts): this. * src/print.c (print_core, print_actions, print_state) (print_grammar): Dump to a file instead a `output_obstack'. (print_results): Dump `output_obstack', and then proceed with the FILE *. * src/files.c (compute_output_file_names, close_files): New. (output_files): Adjust. * src/main.c (main): Adjust.
