+
+	* data/glr.c (yyresolveLocations): Remove bogus YYASSERT that the
+	state before an empty RHS is always resolved here.  Only the location
+	of that state is guaranteed to be resolved, and that's enough.  This
+	fixes the remaining bug reported by Derek M. Jones in
+	<http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00027.html>.
+	* tests/glr-regression.at (Uninitialized location when reporting
+	ambiguity): Test the above case.
+	Also, the embedded comments in this test case claim it checks the case
+	of an empty RHS that has inherited the initial location.  However, the
+	corresponding LHS was already resolved, so yyresolveLocations didn't
+	actually have reason to modify it.  Fix this by forcing
+	nondeterministic operation at the beginning of the parse.

+
+	* data/c.m4 (b4_yy_symbol_print_generate):
+	(b4_yy_symbol_print_generate): Use 'YYSTYPE const' rather than
+	'const YYSTYPE', and similarly for YYLTYPE.  This fixes one
+	of the bugs reported today by Derek M Jones in
+	<http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00027.html>.
+	* doc/bison.texinfo (Value Type): Document that YYSTYPE must be
+	defined to be a type name without parens or brackets.
+	(Location Type): Similarly for YYLTYPE.
+	* tests/regression.at (Trivial grammars): Put in a test for this
+	bug that will be caught by 'make maintainer-check' (though not,
+	alas, by 'make check' unless your compiler is picky).
+
+2006-05-19  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* NEWS: Version 2.2.
+	* configure.ac (AC_INIT): Likewise.
+
+2006-05-17  Joel E. Denny  <jdenny@ces.clemson.edu>
+
+	* data/glr.c (yyreportTree): Make room in yystates for the state
+	preceding the RHS.  This fixes the segmentation fault reported by Derek
+	M. Jones in
+	<http://lists.gnu.org/archive/html/help-bison/2006-05/msg00035.html>.
+	(yyreportTree, yypdumpstack): Subtract 1 from yyrule before printing
+	to the user.  Reported for yyreportTree by Derek M. Jones later in the
+	same thread.
+	* THANKS: Add Derek M. Jones.
+	Update my email address.
+	Fix typo in Steve Murphy's name.
+
+2006-05-14  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* data/glr.c (yyreportSyntaxError): Fix off-by-one error in
+	checking against YYLAST that caused the parser to miss a potential
+	alternative in its diagnostic.
+	Problem reported by Maria Jose Moron Fernandez in
+	<http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00024.html>.
+	* data/lalr1.cc (yysyntax_error_): Likewise.
+	* data/yacc.c (yysyntax_error): Likewise.
+	* tests/regression.at (_AT_DATA_DANCER_Y): Use static array for
+	tokens, in case we run into an older C compiler.
+	(_AT_DATA_EXPECT2_Y, AT_CHECK_EXPECT2): New macros.
+	Use them to check for the off-by-one error fixed above.
+
+	* data/yacc.c (yytnamerr): Fix typo: local var should be of type
+	YYSIZE_T, not size_t.
+	* tests/regression.at (Trivial grammars): New test, to catch
+	the error fixed by the above patch.
+
+2006-05-14  Akim Demaille  <akim@lrde.epita.fr>
+
+	* doc/bison.texinfo (C++ Bison Interface): Clarify the naming
+	scheme.
+	Reported by Steve Murphy.

 	* data/glr.cc, data/lalr1.cc: Using %defines is mandatory.
