+
+       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.

+       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.

+
+       * NEWS: Reword the post-2.3 change to not be so optimistic about

+       (gram_set_out, gram_get_debug, gram_set_debug, gram_lex_destroy):
+       Move these declarations, and...
+       (obstack_for_string, STRING_GROW, STRING_FINISH, STRING_FREE):
+       these to...
+       * src/flex-scanner.h: this new file.
+       * src/scan-gram.l (rule_length, rule_length_overflow)
+       (increment_rule_length): Remove.
+       (last_braced_code_loc): Rename as...
