+
+	* gen-soccon.c: New utility program to generate g-soccon.ads
+	automatically.
+
+	* socket.c, gsocket.h: Split inclusion of system header files into a
+	gsocket.h file separated from socket.c, to allow reuse in gen-soccon.c.
+
+	* g-soccon.ads, g-soccon-unixware.ads, g-soccon-tru64.ads,
+	g-soccon-aix.ads, g-soccon-irix.ads, g-soccon-hpux.ads,
+	g-soccon-interix.ads, g-soccon-solaris.ads, g-soccon-mingw.ads,
+	g-soccon-vxworks.ads, g-soccon-freebsd.ads: Note that these files
+	should not be edited by hand anymore, but should be regenerated using
+	gen-soccon.

+
+	* s-atacco.ads, a-direio.adb: Protect use of 'Constrained by warnings

+	a warning.
+
+	* sem_attr.adb (Analyze_Attribute, case Constrained): Issue warning if
+	warning mode is set and obsolescent usage of this attribute occurs.
+	(Resolve_Access, case 'Access): Note that GNAT uses the context type to
+	disambiguate overloaded prefixes, in accordance with AI-235. GNAT code
+	predates, and partly motivates, the adoption of the AI.
+	Implement new Ada 2005 attribute Mod
+
+	* exp_attr.adb (Expand_N_Attribute_Reference): Implement Ada 2005
+	attribute Mod.

+	No_Obsolescent_Features.
+
+	* s-rident.ads: Add new restriction No_Obsolescent_Features.
+
+	* ali.ads, ali.adb: Adjustments for reading new No_Dependence
+	restrictions lines.
+	(Scan_ALI): When finding an unexpected character on an R line, raise
+	exception Bad_R_Line, instead of calling Fatal_Error, so that, when
+	Ignore_Errors is True, default restrictions are set and scanning of the
+	ALI file continues with the next line. Also, when Bad_R_Line is raised
+	and Ignore_Errors is True, skip to the end of le line.
+
+	* sem_ch10.adb: Check that explicit with's do not violate
+	No_Dependence restrictions.

+
+	* decl.c (compatible_signatures_p): New function. The intended purpose
+	is to check if two function signatures for a call-site and a callee are
+	compatible enough for the call to be valid. The underlying purpose is

+	array is checked after using the index in the array.
+
