+	* tests/push.at: Remove "Push Parsing: " from test group titles
+	because these are already under the banner "Push Parsing Tests".

+	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.
