+       Fix complaints about escape sequences.
+       Discussed starting at
+       <http://lists.gnu.org/archive/html/bison-patches/2009-08/msg00036.html>.
+       * src/scan-gram.l (SC_ESCAPED_STRING, SC_ESCAPED_CHARACTER):
+       For a \0 and similar escape sequences meaning the null
+       character, report an invalid escape sequence instead of an
+       invalid null character because the latter does not actually
+       appear in the user's input.
+       In all escape sequence complaints, don't escape the initial
+       backslash, and don't quote when the sequence appears at the end
+       of the complaint line unless there's whitespace that quotearg
+       won't escape.
+       Consistently say "invalid" not "unrecognized".
+       Consistently prefer "empty character literal" over "extra
+       characters in character literal" warning for invalid escape
+       sequences; that is, consistently discard those sequences.
+       * tests/input.at (Bad escapes in literals): New.
+

+       * doc/bison.texinfo: Fix minor Texinfo errors.
+

+
+       tests: distcc compliance.
+       * tests/synclines.at (AT_SYNCLINES_COMPILE): Discard distcc's
+       error messages from the output.

+       variables: simplify the upgrade of namespace into api.namespace.
+
+       This patch simplifies "variables: rename namespace as
+       api.namespace", commit 67501061076ba46355cfd9f9361c7eed861b389c.
+       Suggested by Joel E. Denny in
+       http://lists.gnu.org/archive/html/bison-patches/2009-07/msg00006.html
+
+       * src/muscle-tab.c (muscle_percent_variable_update): New.
+       (muscle_percent_define_insert): Use it in replacement of the
+       previous tr invocation.
+       Remove variable_tr, no longer needed.
+       * data/bison.m4 (b4_percent_define_copy_, b4_percent_define_copy):
+       Remove.
+       * data/c++.m4: No longer handle namespace -> api.namespace.
+       * tests/input.at (%define backward compatibility): Check that
+       namespace is treated as api.namespace.

+       doc: %initial-action to initialize yylloc.
+       Reported by Bill Allombert.
+       * doc/bison.texinfo: Set fill-column to 76.
+       (Location Type): Document the use of %initial-action to initialize
+       yylloc.

+
+       lalr1.cc: use state_type.
+       * data/lalr1.cc (yysyntax_error_): Use state_type.
+       Move argument names into yy*.
+
+2009-08-19  Akim Demaille  <demaille@gostai.com>
+
+       lalr1.cc: get rid of yyparse's yystate.
+       yystate and yystack_[0].state are equal, keep only the latter.
+       The former was also used as a temporary variable to compute the
+       post-reduction state.  Move this computation into an auxiliary
+       function.
+
+       * data/glr.c (yyLRgotoState): Fuse variable definition and first
+       assignment.
+       * data/lalr1.cc (yy_lr_goto_state_): New.
+       (yyparse): Use it.
+       Replace remaining uses of yystate by yystate_[0].state.
+       Remove the former.

        lalr1.cc: destroy $$ when YYERROR is called.
