glibc/locale/locarchive.h
Ulrich Drepper 705341a92f * locale/locarchive.h (struct locarhandle): Rename len field to
mmaped and add new reserved field.
	* locale/programs/locarchive.c (RESERVE_MMAP_SIZE): Define.
	(create_archive): Reserve address space and then map file into it.
	(open_archive): Likewise.
	(file_data_available_p): New function.
	(compare_from_file): New function.
	(close_archive): Adjust to member name changes.
	(add_locale): Before comparing locale data, check it is mapped.
	Otherwise fall back to reading from the file.
