+       * src/nullable.c (set_nullable): Useless rules must be skipped,
+       otherwise, since we range over their symbols, we might look at a
+       nonterminal which no longer ``exists'', i.e., it is not counted in
+       `nvars', hence we overflow our arrays.

+
+       The header can also be produced directly, without any obstack!
+       Yahoo!
+
+       * src/files.c, src/files.h (defines_obstack): Remove.
+       (compute_header_macro): Global.
+       (defines_obstack_save): Remove.
+       * src/reader.c (parse_union_decl): No longer output to
+       defines_obstack: its content can be found in the `stype' muscle
+       anyway.
+       (output_token_translations): Merge into...
+       (symbols_output): this.
+       Rename as...
+       (symbols_save): this.
+       (reader): Adjust.
+       * src/output.c (header_output): New.
+       (output): Call it.

+
+       * src/reader.c (parse_union_decl): Instead of handling two obstack
+       simultaneously, use one to define the `stype' muscle, and use the
+       value of the latter to fill defines_obstack.
+       (copy_comment): Remove.
+       (copy_comment2): Work for a single obstack.
+       Rename as...
+       (copy_comment): this.

+       * src/lex.c, src/lex.h (xgetc): No longer static.
+       * src/reader.c (parse_union_decl): Revamp.

+
+       Still making progress in separating Bison into (i) input, (ii)
+       process, (iii) output: now we can directly output the parser file
+       without using table_obstack at all.
+
+       * src/files.c, src/files.h (table_obstack): Bye bye.
+       (parser_file_name): New.
+       * src/files.c (compute_output_file_names): Compute it.
+       * src/output.c (actions_output, output_parser)
+       (output_master_parser): To a file instead of an obstack.

        Attach actions to rules, instead of pre-outputting them to
