+
+ 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.

+ 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.

+ Move argument names into yy*.

+
+ 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.

+2009-08-19 Akim Demaille <demaille@gostai.com>
+
+ lalr1.cc: destroy $$ when YYERROR is called.
+ * data/lalr1.cc (yyreduce): Compute the resulting state before
+ running the user action so that yylhs is a valid symbol.
+ (yyerrorlab): Since yylhs is complete (it knows its type), we can
+ simply call yy_destroy_ to destroy $$ on YYERROR invocations.
+ * tests/c++.at (AT_CHECK_VARIANTS): Test YYERROR with variants.

+ build: require gettext 0.17.
+
+ Suggested by Bruno Haible.
+ http://lists.gnu.org/archive/html/bug-bison/2009-08/msg00009.html
+ * configure.ac: require gettext 0.17 to ensure compatibility with
+ gnulib.

+
+ build: lower gettext requirements.
+
+ Bison was uselessly requiring the formatstring macros from
+ gettext, which resulted in mo files not being installed on systems
+ that perfectly supported Bison mo files. Lower the requirement.
+ http://lists.gnu.org/archive/html/bug-bison/2009-08/msg00006.html
+
+ * configure.ac: Require need-ngettext instead of
+ need-formatstring-macros.
