	Preliminary support for Objective-C:
	* defs.h (language_objc): New enum value.
	(puts_filtered_tabular): Declaration only, exported from utils.c.
	(skip_quoted): Delete, declared in completer.h.
	* c-exp.y: Include completer.h.
	* p-exp.y: Ditto.
	* jv-exp.y: Ditto.
	* expression.h (OP_MSGCALL, OP_SELECTOR, OP_SELF, OP_NSSTRING):
	New operator enum values.
	* language.h (CAST_IS_CONVERSION): Test for language_objc.
	* language.c (binop_result_type): Handle language_objc case.
	(integral_type, character_type, string_type, boolean_type,
	structured_type, binop_type_check): Ditto.
	* symtab.h (SYMBOL_OBJC_DEMANGLED_NAME): Define.
	(struct objc_specific): Add to general_symbol_info.
	(SYMBOL_INIT_LANGUAGE_SPECIFIC): Add objc initialization.
	(SYMBOL_DEMANGLED_NAME): Handle objc case.
	* parser-defs.h (struct objc_class_str): New struct type.
	(start_msglist, end_msglist, add_msglist): Declaration only,
	exported from objc-lang.c.
	* value.h (value_of_local, value_nsstring,
	call_function_by_hand_expecting_type): Exported from valops.c.
	* valops.c (find_function_addr): Export.
	(call_function_by_hand_expecting_type): New function.
	(value_of_local): New function.
	* symfile.c (init_filename_language_table): Add ".m" extension
	for Objective-C.
	* utils.c (puts_filtered_tabular): New function.
	(fprintf_symbol_filtered): Add objc demangling support (disabled).
	(set/show demangle): Extend help-string to refer to ObjC.
	* elfread.c (elf_symtab_read): Skip Objective-C special symbols.
	* stabsread.c (symbol_reference_defined): Objective-C symbols
	may contain colons: make allowances when scanning stabs strings
	for colons.
	(objc_find_colon): New function.
	* printcmd.c (address_info): If language == objc then print
	"self" instead of "this".
	* parse.c (length_of_subexp): Handle new operators OP_MSGCALL,
	OP_NSSTRING, and OP_SELF.
	(prefixify_subexp): Ditto.
	* source.c (print_source_lines): Mention objc in comment.
	* breakpoint.c (parse_breakpoint_sals): Recognize Objective-C
	method names.
