+       * NEWS: Don't document %no-default-prec, as it's still
+       too experimental.
+       * doc/bison.texinfo: Document %no-default-prec only if
+       the defaultprec flag is set.  Normally it's not.

+
+       * data/glr.c (b4_rhs_value, b4_rhs_location): Yield a
+       non-modifiable lvalue, instead of a modifiable one.
+       * doc/bison.texinfo (Actions): Document that $$ can
+       be assigned to.  Do not claim that $$ and $N are
+       array element references: user code should not rely on this.

+
+       When reducing initial empty rules, Bison parser read an initial
+       location that is not defined.  This results in garbage, and that
+       affects Bison's own parser.  Therefore we need (i) to extend Bison
+       to support a means to initialize this location, and (ii) to use
+       this CVS Bison to fix CVS Bison's parser.
+
+       * src/reader.h, reader.c (epilogue_augment): Remove, replace
+       with...
+       * src/muscle_tab.h, src/muscle_tab.c (muscle_code_grow): this.
+       * src/parse-gram.y: Adjust.
+       (%initial-action): New.
+       (%error-verbose): Since we require CVS Bison, there is no reason
+       not to use it.
+       * src/scan-gram.l: Adjust.
+       * src/Makefile.am (YACC): New, to make sure we use our own parser.
+       * data/yacc.c (yyparse): Use b4_initial_action.
+
+2003-08-25  Akim Demaille  <akim@epita.fr>
+
+       * doc/bison.texinfo: Don't promote stdout for error messages.
