+
+	Improve C++ namespace support.  Discussed starting at
+	<http://lists.gnu.org/archive/html/help-bison/2007-09/msg00016.html>.
+	* data/c++.m4: (b4_namespace_ref, b4_namespace_open,
+	b4_namespace_close): New macros that interpret the %define variable
+	"namespace" so its value can contain "::" to indicate nested
+	namespaces.
+	* data/glr.cc (b4_namespace): Don't define, and replace all uses with
+	the above macros.
+	* data/lalr1.cc (b4_namespace): Likewise.
+	* data/location.cc (b4_namespace): Likewise.
+	* doc/bison.texinfo (Decl Summary): Move `%define push_pull' entry
+	inside a new table in the general %define entry.  Document `%define
+	namespace' there as well.  Point the %name-prefix entry to it since it
+	explains it more completely in the case of C++.
+	(C++ Bison Interface): Mention `%define namespace' instead of
+	%name-prefix.
+	(Table of Symbols): Remove the `%define push_pull' entry.  The %define
+	entry suffices.
+	* tests/c++.at (Relative namespace references): New test case.
+	(Absolute namespace references): New test case.
+	(Syntactically invalid namespace references): New test case.
+	* tests/input.at (C++ namespace reference errors): New test case.

+
+	Add syncline support and location accessor to internal %define
+	interfaces.
+	* data/bison.m4 (b4_percent_define_get_loc): New.
+	(b4_percent_define_get_syncline): New.
+	(b4_percent_define_flag_if): Use b4_percent_define_get_loc.
+	(b4_percent_define_default): Record defining location as line 1 rather
+	than 0 for the sake of synchronizing #line's, and define
+	b4_percent_define_syncline(VARIABLE).
+	(b4_percent_define_check_values): Use b4_percent_define_get_loc.
+	* src/muscle_tab.c (muscle_syncline_grow): New.
+	(muscle_code_grow): Use muscle_syncline_grow.
+	(muscle_percent_define_insert): Use muscle_percent_define_get_loc, and
+	define b4_percent_define_syncline(VARIABLE).
+	(muscle_percent_define_get_loc): New.
+	(muscle_percent_define_get_syncline): New.
+	(muscle_percent_define_flag_if): Use muscle_percent_define_get_loc, and
+	remove some unused variables.
+	(muscle_percent_define_default): Record defining location as line 1
+	rather than 0 for the sake of synchronizing #line's, and define
+	b4_percent_define_syncline(VARIABLE).
+	(muscle_percent_define_check_values): Use
+	muscle_percent_define_get_loc.
+	* src/muscle_tab.h (muscle_percent_define_get_loc): Prototype.
+	(muscle_percent_define_get_syncline): Prototype.
+	* tests/skeletons.at (%define Boolean variables: invalid skeleton
+	defaults): Update output for location change.
+	(Complaining during macro argument expansion): Extend to test
+	b4_percent_define_get_loc and b4_percent_define_get_syncline errors.
+
+2007-10-07  Joel E. Denny  <jdenny@ces.clemson.edu>
+
+	Fix some error-reporting macro bugs.
+	* data/bison.m4 (b4_cat): New.
+	(b4_error, b4_error_at): Use b4_cat to send error directives directly
+	to stdout so they don't become arguments to other macros.  Update
+	comments and add examples.
+	(b4_warn, b4_warn_at, b4_complain, b4_complain_at): Update comments and
+	add examples.
+	(b4_fatal, b4_fatal_at): Likewise, and invoke m4_exit(1) immediately
+	after printing the error directive so that M4 doesn't report subsequent
+	problems that are induced by this problem.
+	* src/scan-skel.l: Recognize @` digraph outside of directive arguments
+	instead of just in them.  Recognize @\n in both places.  Both expand to
+	the empty string.  Needed by b4_cat.
+	* tests/skeletons.at (Complaining during macro argument expansion):
+	New test case.
+	(Fatal errors make M4 exit immediately): New test case.
