+       Provide an additional sub-message for clarity.
+       Add "symbol not found in production" error message when
+       an "invalid reference" is detected in named references
+       resolution.
+       * src/scan-code.l: Update "invalid reference" case.
+       * tests/named-ref.at: Adjust test-cases.

+
+       Clean up yacc.c a little.
+       * data/yacc.c: Clean up M4 for readability, and make output
+       whitespace more consistent.  For the main parse function
+       comment, instead of saying "yyparse or yypush_parse", say either
+       "yyparse" or "yypush_parse" depending on which it actually is.

+
+       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.
