Subject: cpperror.c (cpp_file_line_for_message): Constify a char*.

	* cpperror.c (cpp_file_line_for_message): Constify a char*.

	* cppexp.c (parse_number, parse_charconst, cpp_lex,
	cpp_parse_expr): Add static prototypes.
	(parse_charconst): Don't cast away const-ness.
	(token): Constify a char*.

	* cppfiles.c (file_name_list, include_hash, find_include_file,
	finclude, initialize_input_buffer): Constify a char*.
	(file_cleanup, find_position): Add static prototypes.

	* cpphash.c (macro_cleanup, macarg, timestamp, special_symbol,
	collect_expansion): Add static prototypes.
	(cpp_install, create_definition, monthnames): Constify a char*.

	* cpphash.h (cpp_install): Likewise.

	* cppinit.c (known_suffixes, default_include,
	dump_special_to_buffer, NAME, cpp_start_read, cpp_finish): Likewise.
	(base_name, dump_special_to_buffer, initialize_dependency_output):
	Add static prototypes.

	* cpplib.c (my_strerror): Constify a char*.
	(null_underflow, null_cleanup, skip_comment, copy_comment,
	copy_rest_of_line, handle_directive, pass_thru_directive,
	get_directive_token, read_line_number, cpp_print_file_and_line,
	v_cpp_error, v_cpp_warning, v_cpp_error_with_line,
	v_cpp_warning_with_line, detect_if_not_defined,
	consider_directive_while_skipping): Add static prototypes.
	(pass_thru_directive, check_macro_name, cpp_expand_to_buffer,
	cpp_pedwarn_with_file_and_line): Constify a char*.

	* cpplib.h (cpp_options, include_hash, progname, definition,
	cpp_pedwarn_with_file_and_line, cpp_expand_to_buffer,
	check_macro_name, cpp_pfatal_with_name, cpp_file_line_for_message,
	find_include_file, deps_output, include_hash): Constify a char*.

	* cppmain.c (progname): Constify.
	(main): Add prototype.  Use return, not exit.

	* fix-header.c (fatal, add_symbols, lookup_std_proto, write_lbrac,
	recognized_macro, check_macro_names, read_scan_file, write_rbrac,
	inf_skip_spaces, inf_read_upto, inf_scan_ident, inf_scan_ident,
	check_protection): Add static prototype.
	(xfree): Remove.
	(progname, recognized_macrom, recognized_extern): Constify a char*.
	(main): Add prototype.

	* gen-protos.c (progname): Constify a char*.
