Log message:
	2004-09-20  Matt Austern <austern@apple.com>
	Zack Weinberg  <zack@codesourcery.com>
	
	* c-common.c (fix_string_type): Build the unqualified array
	type unconditionally, then use c_build_qualified_type to get
	the proper const-qualified variant, and set its
	TYPE_MAIN_VARIANT to refer to the unqualified type.
	* c-lex.c (c_lex_return_raw_string): New global.
	(c_lex_with_flags): Honor it.
	* c-pragma.h: Declare it.
	
	cp:
	* decl.c (make_rtl_for_nonlocal_decl, start_preparsed_function):
	Apply lbasename to input_filename before passing to get_fileinfo.
	* semantics.c (begin_class_definition): Likewise.
	* lex.c (handle_pragma_interface): Apply get_fileinfo to the
	correct filename.  Rename variables to be less confusing.
	(handle_pragma_implementation): Likewise.  Disable "appears
	after file is included" diagnostic.
	
	* parser.c (struct cp_token): Add in_system_header fiag.
	(CP_TOKEN_BLOCK_NUM_TOKENS, struct cp_token_block)
	(CP_TOKEN_BUFFER_SIZE, cp_token_cache_push_token)
	(CPP_NONE, cp_lexer_read_token): Delete.
	(struct cp_lexer): Remove first_token, string_tokens,
	main_lexer_p fields.  Clarify comments.
	(struct cp_token_cache): Now just a pair of pointers.
	(CP_LEXER_BUFFER_SIZE): New #define.
	(CPP_PURGED): New fake token type.
	(cp_lexer_new_from_token_array, cp_lexer_destroy)
	(cp_lexer_peek_token_emit_debug_info, cp_lexer_skip_purged_tokens)
	(cp_lexer_handle_pragma, cp_token_cache_new, cp_parser_string_literal):
	New functions.
	(cp_lexer_new_from_tokens): Now a simple wrapper around
	cp_lexer_new_from_token_array.
	(cp_lexer_set_source_position_from_token): Also update
	in_system_header.
	(cp_lexer_next_token, cp_lexer_prev_token, cp_lexer_advance_token):
	Don't wrap round.
	(cp_lexer_token_difference): Dont handle wrapping round.
	(cp_lexer_new_main): Enable pragma deferral and raw strings,
	read the entire translation unit through c_lex_with_flags into
	this lexer's buffer, then turn raw strings back off again.
	(cp_lexer_grow_buffer): Adjust for buffer no longer being circular.
	(cp_lexer_get_preprocessor_token): No need to handle not being
	the main lexer.  Set token->in_system_header too.
	(cp_lexer_peek_token): Skip purged tokens.  Feed pragma tokens
	to cp_lexer_handle_pragma.  No need to call cp_lexer_read_token.
	(cp_lexer_peek_nth_token): Likewise.
	(cp_lexer_purge_token): Mark the token PURGED, don't shift all
	the other tokens down.
	(cp_lexer_purge_tokens_after): Likewise.
	(cp_lexer_save_tokens, cp_lexer_rollback_tokens): Don't worry
	about there being no tokens.
	(cp_lexer_print_token): Revise to give useful information on
	all tokens.
	(struct cp_parser): Add field translate_strings_p.
	(cp_parser_new): Initialize it.
	(cp_parser_translation_unit): Destroy the lexer when done.
	(cp_parser_parameter_declaration): Restructure saving of
	default arguments.
	(cp_parser_save_member_function_body): Likewise.
	(cp_parser_check_for_invalid_template_id)
	(cp_parser_nested_name_specifier_opt, cp_parser_template_id):
	Adjust calls to cp_lexer_advance_token.
	(cp_parser_skip_to_closing_parenthesis, cp_parser_declaration):
	No need to fiddle c_lex_string_translate.
	(cp_parser_primary_expression, cp_parser_linkage_specification)
	(cp_parser_asm_definition, cp_parser_asm_specification_opt)
	(cp_parser_asm_operand_list, cp_parser_asm_clobber_list)
	Use cp_parser_string_literal.
	(cp_parser_attribute_list): Save and restore
	parser->translate_strings_p, not c_lex_string_translate.
	(cp_parser_cache_group): Delete.
	(cp_parser_cache_group_1): Rename cp_parser_cache_group.  Do
	not take a cache argument.
