+       Add %expect-rr rule.
+       
+       * src/scan-gram.l: Recognize %expect-rr.
+
+       * src/conflicts.h (expected_sr_conflicts): Rename from 
+       expected_conflicts.
+       (expected_rr_conflicts): Declare.       
+
+       * src/conflicts.c (expected_sr_conflicts): Rename from
+       expected_conflicts.
+       (expected_rr_conflicts): Define.
+       (conflicts_print): Check r/r conflicts against expected_rr_conflicts
+       for GLR parsers.
+       Use expected_sr_conflicts in place of expected_conflicts.
+       Warn if expected_rr_conflicts used in non-GLR parser.
+

+       Add support for hex token numbers.  Suggested by Odd Arild Olsen in
+       <http://mail.gnu.org/archive/html/bison-patches/2004-03/msg00000.html>.
+
+       * NEWS: Document hexadecimal tokens, no NUL bytes, %destructor
+       in lalr1.cc.
+       * doc/bison.texinfo (Token Decl): Add hexadecimal token numbers.
+       * src/scan-gram.l (scan_integer): New function.
+       ({int}): Use it.
+       (0[xX][0-9abcdefABCDEF]+): New pattern, to support hex numbers.
+       (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER>, \\x[0-9abcdefABCDEF]+,
+       handle_action_dollar, handle_action_at, convert_ucn_to_byte):

+       * tests/local.at (AT_COMPILE, AT_COMPILE_CXX): Ignore stdout from
+       compilers.  This fixes a problem with Intel's C++ compiler being
+       chatty, reported by Guido Trentalancia in
+       <http://mail.gnu.org/archive/html/bug-bison/2004-02/msg00030.html>.
