	* locale/hashval.h (compute_hashval): Use prototype defn.
	(hashval_t): New macro, defined to unsigned long int
	if not already defined.
	(compute_hashval): Return hashval_t instead of unsigned long int.
	* locale/loadarchive.c (hashval_t): New macro.
	* locale/programs/locarchive.c: Include hashval.h directly instead
	of simple-hash.h.
	(compute_hashval, hashval_t): Define these macros first.
	(insert_name): Use archive_hashval instead of compute_hashval.
	(add_locale, delete_locales_from_archive): Likewise.
