+
+ Don't put the pre-prologue in the header file. For the yacc.c code
+ file and the glr.c header and code files, move the pre-prologue before
+ the token definitions. Add new %before-definitions and
+ %after-definitions to declare code that will go in both the header file
+ and code file. Discussed at
+ <http://lists.gnu.org/archive/html/bison-patches/2005-12/msg00000.html>,
+ <http://lists.gnu.org/archive/html/bison-patches/2006-01/msg00016.html>,
+ and
+ <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00055.html>.
+ * NEWS (2.3+): Describe these changes.
+ * data/glr.c (b4_pre_prologue): Move from within to before...
+ (b4_shared_declarations): ... this.
+ Add new b4_before_definitions before b4_token_enums.
+ Add new b4_after_definitions at the end.
+ * data/glr.cc (b4_pre_prologue): Replace with...
+ (b4_before_definitions): ... this in the header file.
+ (b4_after_definitions): New near the end of the header file.
+ * data/lalr1.cc (b4_pre_prologue): Move from the header file to the
+ code file right before including the header file.
+ (b4_before_definitions): New in the previous position of
+ b4_pre_prologue in the header file.
+ (b4_after_definitions): New near the end of the header file.
+ * data/yacc.c: Clean up some m4 quoting especially in the header file.
+ (b4_token_enums_defines): In the code file, move to right before
+ YYSTYPE for consistency with the header file.
+ (b4_before_definitions): New right before b4_token_enums_defines in
+ both the header and code file.
+ (b4_after_definitions): New right after YYLTYPE and yylloc in both the
+ header and code file.
+ * doc/bison.texinfo (Prologue): Show use of %before-definitions instead
+ of prologues for %union dependencies.
+ (Bison Declaration Summary): In %defines description, mention the
+ effect of %before-definitions and %after-definitions on the header
+ file.
+ (Calc++ Parser): Forward declare driver in a %before-definitions rather
+ than in the pre-prologue so that make check succeeds.
+ (Bison Symbols): Add entries for %before-definitions and
+ %after-definitions.
+ * src/parse-gram.y (PERCENT_BEFORE_DEFINITIONS): New token for
+ %before-definitions.
+ (PERCENT_AFTER_DEFINITIONS): New token for %after-definitions.
+ (declaration): Parse those declarations and append to
+ b4_before_definitions and b4_after_definitions, respectively.
+ * src/reader.c (before_definitions, after_definitions): New bools to
+ track whether those declarations have been seen.
+ (prologue_augment): Add to the post-prologue if %union,
+ %before-definitions, or %after-definitions has been seen.
+ * src/reader.h (before_definitions, after_definitions): New extern's.
+ * src/scan-gram.l: Scan the new declarations.
+ * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Place the second
+ prologue block in a %before-definitions or a %after-definitions based
+ on whether the %union is declared.
+ * tests/regression.at (Early token definitions with --yacc, Early token
+ definitions without --yacc): Move tests for token definitions into the
+ post-prologue since token names are no longer defined in the
+ pre-prologue.

+
+ * src/symtab.h, src/symtab.c (symbol_from_uniqstr): New.
+ (symbol_get): Use it.
+ * src/parse-gram.y: Use it.
+
+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.
+

+
+ * 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.

+
+ * 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.
