+
+       lalr1.cc: syntax_error as exceptions.
+       It is common to use sort of factories in the user actions.  These
+       factories may check some "syntactic" constraints that are not
+       enforced by the grammar itself.  This is possible using YYERROR
+       within the action itself.  Provide the user with a means to throw
+       a syntax_error exception.
+
+       * data/c++.m4 (b4_public_types_declare, b4_public_types_define):
+       Declare and define yy::parser::syntax_error.
+       * data/lalr1.cc: Include stdexcept.
+       (yy::parser::parse): Wrap the user action within a try/catch.
+       * data/glr.cc: Include stdexcept.
+
+2009-09-09  Akim Demaille  <demaille@gostai.com>
+
+       lalr1.cc: add missing "inline".
+       * data/c++.m4 (b4_public_types_define): Add missing inline to
+       implementations provided in headers.
+
+2009-09-09  Akim Demaille  <demaille@gostai.com>
+
+       %param: documentation.
+       * NEWS (2.6): Document %param, %lex-param, and %parse-param
+       changes.
+       * doc/bison.texinfo: Document that %lex-param and %parse-param
+       are n-ary.
+       Changes some examples to demonstrate it.
+       (Calc++ Parser): Use %param.

+       * src/parse-gram.y (current_param): New.
+       (param_type): Add param_none.
+       (params): New nonterminal.
+       Use it.

+       %param.
+       Provide a means to factor lex-param and parse-param common
+       declarations.
+
+       * src/parse-gram.y (param_type): New.
+       Define a %printer for it.
+       (add_param): Use it.
+       (%parse-param, %lex-param): Merge into...
+       (%parse): this new token.
+       Adjust the grammar to use it.
+       * src/scan-gram.l (RETURN_VALUE): New.
+       (RETURN_PERCENT_FLAG): Use it.
+       (RETURN_PERCENT_PARAM): New.
+       Use it to support %parse-param, %lex-param and %param.
