+
+       Since we now use obstacks, more % directives can be enabled.
+
+       * src/lex.c (percent_table): Also accept `%yacc',
+       `%fixed_output_files', `%defines', `%no_parser', `%verbose', and
+       `%debug'.
+       Handle the actions for `%semantic_parser' and `%pure_parser' here,
+       instead of returning a token.
+       * src/lex.h (SEMANTIC_PARSER, PURE_PARSER): Remove, unused.
+       * src/reader.c (read_declarations): Adjust.
+       * src/files.c (open_files): Don't call `compute_base_names', don't
+       compute `attrsfile' since they depend upon data which might be
+       *in* the input file now.
+       (output_files): Do it here.
+       * src/output.c (output_headers): Document the fact that this patch
+       introduces a guaranteed SEGV for semantic parsers.
+       * doc/bison.texinfo: Document them.
+       * tests/suite.at: Exercise these %options.
+
+2000-12-20  Akim Demaille  <akim@epita.fr>
+
+       Also handle the output file (--verbose) with obstacks.
+
+       * files.c (foutput): Remove.
+       (output_obstack): New.
+       Adjust all dependencies.
+       * src/conflicts.c: Return a string.
+       * src/system.h (obstack_grow_string): Rename as...
+       (obstack_sgrow): this.  Be ready to work with non literals.
+       (obstack_fgrow4): New.
+
+2000-12-20  Akim Demaille  <akim@epita.fr>
+
+       * src/files.c (open_files): Fix the computation of short_base_name
+       in the case of `-o foo.tab.c'.
+
+2000-12-20  Akim Demaille  <akim@epita.fr>
+
+       * src/reader.c (copy_string, copy_comment, copy_comment2, copy_at)
+       (copy_dollar): Now that everything uses obstacks, get rid of the
+       FILE * parameters.
+
+2000-12-20  Akim Demaille  <akim@epita.fr>
+
+       * src/files.c (open_files): Actually the `.output' file is based
+       on the short_base_name, not base_name.
+       * tests/suite.at (Checking output file names): Adjust.
+
+2000-12-20  Akim Demaille  <akim@epita.fr>
+
+       * src/bison.s1: Remove, we now use directly...
+       * src/bison.simple: this.
+       * src/Makefile.am: Use pkgdata instead of data.
+
+2000-12-20  Akim Demaille  <akim@epita.fr>
+
+       * src/files.c (guard_obstack): New.
+       (open_files): Initialize it.
+       (output_files): Dump it...
+       * src/files.h: Export it.
+       * src/reader.c (copy_guard): Use it.
+
+2000-12-19  Akim Demaille  <akim@epita.fr>
+
+       * src/files.c (outfile, defsfile, actfile): Removed as global
+       vars.
+       (open_files): Don't compute them.
+       (output_files): Adjust.
+       (base_name, short_base_name): Be global.
+       Adjust dependencies.
+
+2000-12-19  Akim Demaille  <akim@epita.fr>
+
+       * src/files.c (strsuffix): New.
+       (stringappend): Be just like strcat but allocate.
+       (base_names): Eve out from open_files.
+       Try to simplify the rather hairy computation of base_name and
+       short_base_name.
+       (open_files): Use it.
+       * tests/suite.at (Checking output file names): New test.
+
+2000-12-19  Akim Demaille  <akim@epita.fr>
+
+       * src/system.h (obstack_grow_literal_string): Rename as...
+       (obstack_grow_string): this.
+       * src/output.c (output_parser): Recognize `%% actions' instead of
+       `$'.
+       * src/bison.s1: s/$/%% actions/.
+       * src/bison.hairy: Likewise.
+
+2000-12-19  Akim Demaille  <akim@epita.fr>
+
+       * src/output.c (output_parser): Compute the `#line' lines when
+       there are.
+       * src/Makefile.am (bison.simple): Be a simple copy of bison.s1.
+       Suggested by Hans Aberg.
+
+2000-12-19  Akim Demaille  <akim@epita.fr>
+
+       Let the handling of the skeleton files be local to the procedures
+       that use it.
+
+       * src/files.c (xfopen, xfclose, skeleton_find, guardfile): No
+       longer static.
+       (fparser, open_extra_files): Remove.
+       (open_files, output_files): Don't take care of fparser.
+       * src/files.h: Adjust.
+       * src/output.c (output_parser): Open and close the file to the
+       skeleton.
+       * src/reader.c (read_declarations): When %semantic_parser, open
+       fguard.
+
+2000-12-19  Akim Demaille  <akim@epita.fr>
+
+       * src/file.h (BISON_SIMPLE, BISON_HAIRY): Move from here...
+       * src/system.h (BISON_SIMPLE, BISON_HAIRY): ... to here.
+
+2000-12-19  Akim Demaille  <akim@epita.fr>
+
+       * src/files.c (open_files): Yipee!  We no longer need all the code
+       looking for `/tmp' since we have no tmp file.
+
+2000-12-19  Akim Demaille  <akim@epita.fr>
+
+       * src/system.h (EXT_TAB, EXT_OUTPUT, EXT_STYPE_H, EXT_GUARD_C):
+       New macros.
+       * src/files.c (open_files): Less dependency on MSDOS etc.
+
+2000-12-14  Akim Demaille  <akim@epita.fr>
+
+       * src/bison.s1 (YYLLOC_DEFAULT): New macro.
+       Provide a default definition.
+       Use it when executing the default @ action.
+       * src/reader.c (reader_output_yylsp): No longer include
+       `timestamp' and `text' in the default YYLTYPE.
+
 2000-12-12  Akim Demaille  <akim@epita.fr>
 
        * src/reader.c (copy_definition, parse_union_decl, copy_action)
