+2006-06-19 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ * src/scan-gram.l: Remove unused declaration of last_string_1 so the
+ build succeeds when configured with --enable-gcc-warnings.
+
+2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
+
+ * src/parse-gram.y (char_name): New function.
+ (CHAR, STRING, string_content): For %printer, properly escape.
+ (ID): Prefer fputs to fprintf.
+ (id): Reindent to be consistent with other rules.
+ Properly quote char.
+
+ The Translation Project changed its way of publishing translations
+ to maintainers. I haven't received any responses to my request
+ for supporting the old way, or for documenting the new way. I
+ have modified 'bootstrap' to use screen scraping
+ (in this case, HTML scraping). This is unreliable and inelegant,
+ but I don't see any better way. Yuck.
+ * bootstrap (TP_URL, WGET_COMMAND): New vars.
+ (get_translations): New function, which uses HTML scraping to
+ deduce locations of latest translations.
+ Use this function to grab both bison and bison-runtime .po files.
+ Don't bother priming the pump for the runtime-po domain any more,
+ as it's now translated better than bison is.
+
+2006-06-19 Akim Demaille <akim@epita.fr>
+
+ * src/scan-gram.l: No longer "parse" things after `%union' until
+ `{'. Rather, return a single "%union" token.
+ No longer make symbols: return strings, and leave the conversion
+ to symbols to the parser.
+ (SC_PRE_CODE, token_type): Remove.
+ * src/parse-gram.y (%union): New field `character'.
+ Sort tokens.
+ (CHAR): New token.
+ (ID, ID_COLON): Now that the scanner no longer makes them
+ identifiers, adjust all uses to invoke symbol_get.
+ (id_colon): New, wraps the conversion from string to symbol.
+ (%union): Accept a possible union_name.
+ (symbol): Now can be a char.
+ * data/c.m4 (b4_union_name): Leave a default value.
+ * data/glr.c, data/yacc.c: Use it.
+
+2006-06-11 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ For associating token numbers with token names for "yacc.c", don't use
+ #define statements unless `--yacc' is specified; always use enum
+ yytokentype. Most important discussions start at:
+ <http://lists.gnu.org/archive/html/bison-patches/2005-09/msg00053.html>,
+ <http://lists.gnu.org/archive/html/bison-patches/2005-12/msg00052.html>,
+ and
+ <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00043.html>.
+ * NEWS (2.3+): Mention.
+ * data/c.m4 (b4_yacc_if): New.
+ (b4_token_enums_defines): Use b4_yacc_if to decide whether to add the
+ token #define's.
+ * doc/bison.texinfo (Bison Options): Describe the effect of `--yacc'
+ on token name definitions.
+ * src/getargs.c (usage): Capitalize `Yacc' in English.
+ * src/output.c (prepare): Define b4_yacc_flag.
+ * tests/regression.at (Early token definitions): Test that tokens names
+ are defined before the pre-prologue not just before the post-prologue.
+ Remove this test case and copy to...
+ (Early token definitions with --yacc): ... this to test #define's.
+ (Early token definitions without --yacc): ... and this to test enums.
+
+2006-06-11 Paul Eggert <eggert@cs.ucla.edu>
+
+ * NEWS: Reword the post-2.3 change to not be so optimistic about
+ removing the old "look-ahead" spelling.
+ Update previous look-ahead/lookahead change reports.
+ * REFERENCES: look-ahead -> lookahead (since that's
+ what he actually wrote).
+ * doc/refcard.tex: look ahead -> lookahead,
+ look-ahead -> lookahead
+
+2006-06-09 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ For consistency, use `lookahead' instead of `look-ahead' or
+ `look_ahead'. Discussed starting at
+ <http://lists.gnu.org/archive/html/bison-patches/2006-01/msg00049.html>
+ and then at
+ <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00017.html>.

+ spellings.

+ Bison without installing the yacc script.
+
+2006-06-07 Joel E. Denny <jdenny@ces.clemson.edu>

+ and yytext if they're already #define'd.
+ * src/flex-scanner.h, src/location.h: Move #include "system.h" to...
+ * src/scan-code-c.c: ... here.

+ <config.h>.
+
+2006-06-07 Joel E. Denny <jdenny@ces.clemson.edu>
+

+2006-06-06 Akim Demaille <akim@epita.fr>
+
+ Extract the parsing of user actions from the grammar scanner.
+ As a consequence, the relation between the grammar scanner and
+ parser is much simpler. We can also split "composite tokens" back
+ into simple tokens.

+ * src/location.h (boundary_set): New.
+ * src/main.c: Adjust to scanner_free being renamed as
+ gram_scanner_free.

+ * src/parse-gram.y: Include scan-gram.h and scan-code.h.
+ Use boundary_set.
+ (PERCENT_DESTRUCTOR, PERCENT_PRINTER, PERCENT_INITIAL_ACTION)
+ (PERCENT_LEX_PARAM, PERCENT_PARSE_PARAM): Remove the {...} part,
+ which is now, again, a separate token.
+ Adjust all dependencies.
+ Whereever actions with $ and @ are used, use translate_code.
+ (action): Remove this nonterminal which is now useless.
+ * src/reader.c: Include assert.h, scan-gram.h and scan-code.h.
+ (grammar_current_rule_action_append): Use translate_code.
+ (packgram): Bound check ruleno, itemno, and rule_length.
+ * src/reader.h (gram_in, gram__flex_debug, scanner_cursor)

+ (handle_action_dollar, handle_action_at): Move to...
+ * src/scan-code.l: here.

+ scan-code.h, scan-code-c.c, scan-gram.h.
+ (EXTRA_bison_SOURCES): Add scan-code.l.
+ (BUILT_SOURCES): Add scan-code.c.
+ (yacc): Be robust to white spaces.
+
