	gcc            : ChangeLog cppinit.c cpplib.c cpplib.h 
	                 cppmacro.c cppfiles.c cppexp.c 

Log message:
	* cppinit.c (builtin_array): Update.
	(init_builtins): Flag builtins to warn if redefined or
	undefined.  Define __GXX_WEAK as a normal macro.
	* cpplib.c (do_undef): Warn if flagged NODE_WARN.
	* cpplib.h (NODE_WARN): New flag.
	* cppmacro.c (builtin_macro): Remove handling of __GXX_WEAK__.
	Handle __STDC__ as a builtin only on Solaris.
	(warn_of_redefinition): Renamed from check_macro_definition.
	Reverse sense of test.  Always warn if NODE_WARN.
	(_cpp_create_definition): Use warn_of_redefinition.  Flag
	any macro beginning with "__STDC_" to require a mandatory
	warning if redefined or undefined.
	* cppinit.c (set_lang):  Move builtin handling to...
	(init_builtins): ...here.
	(_cpp_create_reader): Move call to set_lang.
	* cppfiles.c (stack_include_file): Generate dependencies
	here, and manage include_count here too.
	(PRINT_THIS_DEP): Delete.
	(_cpp_execute_include): Do not generate dependencies here,
	apart from the case of a missing header.  Do not manage
	include_count.
	(_cpp_read_file): Leave dependency generation to
	stack_include_file.
	* cppexp.c (parse_number): Similarly.
	* cpplib.h (NODE_SYSHDR, cpp_sys_objmacro_p): New.
	* cppmacro.c (struct cpp_macro): New member node.
	(parse_args): Only warn about missing rest args if not
	a system macro.
	(funlike_invocation_p): Similarly for uninvoked funlike macros.
	(cpp_sys_objmacro_p): New.
	(_cpp_create_definition): Store the node with the macro defn.
	Remember if the macro is defined in a system header.
