	gcc            : ChangeLog cppexp.c cpphash.c cpphash.h 
	                 cppinit.c cpplex.c cpplib.c cpplib.h 
	                 fix-header.c scan-decls.c 

Log message:
	* cpplib.h (struct cpp_name): Now struct cpp_string.
	(CPP_INT, CPP_FLOAT, CPP_NUMBER, CPP_COMMENT,
	CPP_HEADER_NAME): Change to type S.
	(struct cpp_token): Rename 'name' field to 'str'.  Add 'node'
	field, a cpp_hashnode *.  All references to val.name updated
	to use val.str or val.node as appropriate.
	(struct cpp_reader): Add spec_nodes field.
	(cpp_idcmp): Now cpp_ideq; takes a token * and a char *.
	
	* cpphash.h (struct spec_nodes): New.
	(enum spell_type): Reorder.  Only SPELL_STRING tokens use
	val.str.  All references to 'spelling > SPELL_NONE' updated to
	match.
	
	(CPP_IN_SYSTEM_HEADER): Check pfile->buffer and
	pfile->buffer->inc are not NULL before dereferencing them.
	
	* cpplex.c (parse_name): Take a pointer to the current token,
	plus current position and limit as args; return the new
	position; don't copy the text of a name into the string
	buffer, instead call cpp_lookup and store the node pointer.
	If extending a token, copy out the text of the old into a
	scratch buffer, append the new, look that up and store the new
	node pointer.  Inline.
	(maybe_paste_with_next): If the result of paste is a NAME,
	then look up the pasted text and store its node pointer.
	(lex_line): Adjust for new parse_name interface.
	Check for L"str", L'str' using spec_nodes->n_L.
	(spell_token): SPELL_IDENT tokens have their spelling in
	val.node->name.  Handle SPELL_STRING tokens that don't have
	string delimiters.
	(_cpp_expand_name_space,
	(can_paste): Check for L ## "str" using spec_nodes->n_L.
	(cpp_get_token, special_symbol): No need to call cpp_lookup.
	(cpp_idcmp): Now cpp_ideq; take a token * and a const char *;
	return 1=equal 0=not, not a tristate.
	
	* cpphash.c (var_args_str): Delete.
	(find_param): Compare node fields directly.
	(is__va_args__): Use CPP_PEDANTIC.  Just compare
	token->val.node with spec_nodes->n__VA_ARGS__.
	(dump_funlike_macro): Don't use var_args_str.
	
	* cpplib.c (_cpp_check_directive): Just walk through
	spec_nodes->dirs comparing pointers.
	(get_define_node, do_pragma_poison, detect_if_not_defined,
	parse_ifdef): The identifier has already been looked up.
	(do_ifdef, do_ifndef): parse_ifdef won't return a poisoned
	node.
	(do_if): Only call detect_if_not_defined at beginning of file.
	(_cpp_parse_assertion): Only copy string pointers for
	SPELL_STRING tokens.
	(pragma_dispatch): Take a node pointer and examine its name
	field.
	(_cpp_init_stacks): Also initialize the spec_nodes structure.
	
	* cppinit.c (cpp_reader_init): Call _cpp_init_stacks after
	_cpp_init_macros.
	(cpp_cleanup): Free pfile->spec_nodes.  Call _cpp_cleanup_* in
	reverse order from the corresponding _cpp_init_* routines.
	
	* cppexp.c (parse_number, parse_charconst, parse_defined,
	lex): Check val.node->type instead of calling cpp_defined.
	Use spec_nodes entries where appropriate.
	
	* fix-header.c, scan-decls.c: Update for interface changes.
