+       * NEWS, configure.ac: Bump to 2.1a.
+
+2005-09-16  Paul Eggert  <eggert@cs.ucla.edu>
+
+       * NEWS: Version 2.1.
+
+       * NEWS: Remove notice of yytname change, since it was never in an
+       official release.
+       * data/glr.c (yydestroyGLRState): Rename local var to avoid shadowing
+       diagnostic.
+       * src/output.c (prepare): Likewise.
+       * data/lalr1.cc (YYERROR_VERBOSE_IF): New macro.
+       (yysyntax_error_): Use it to avoid GCC warning when YYERROR_VERBOSE
+       is not defined.  This is an awful hack, but it's enough for now.
+       All callers changed.
+       * tests/glr-regression-at (make_value): Args are const pointers now,
+       to avoid GCC warning.
+       (Duplicated user destructor for lookahead): New test.  Currently
+       skipped.  It fails on my host but I'm not sure it'll always fail.

+
+       * src/symtab.h (struct symbol): Declare the printer and destructor
+       as const, to avoid accidental calls to free.
+       (symbol_destructor_set, symbol_printer_set): Adjust.
+       * src/symtab.c: Adjust.
+

+
+       * data/c.m4 (b4_token_enums): New.
+       (b4_token_defines): Rename as...
+       (b4_token_enums_defines): this.
+       (b4_token_defines): New, output only the #defines.
+       * data/yacc.c, data/glr.c: Adjust.
+       * data/lalr1.cc: Use b4_token_enums instead of b4_token_enums_defines.
+       * data/c.m4 (b4_yydestruct_generate, b4_yysymprint_generate): Define
+       as default values.
+

        * data/lalr1.cc (yylex_): Remove, inline its code.
