Update.
2004-05-25  Ulrich Drepper  <drepper@redhat.com>

	* nss/digits_dots.c (__nss_hostname_digits_dots): Remove typep and
	flags parameter, convert afp to simple int parameter.  Adjust code.
	typep was never != NULL and flags therefore also unused.  *afp is
	never modified.
	* nss/nsswitch.h: Adjust __nss_hostname_digits_dots prototype.
	* nss/getXXbyYY.c: Remove HAVE_TYPE handling.  Adjust af parameter
	handling for __nss_hostname_digits_dots calls.
	* nss/getXXbyYY_r.c: Likewise.

	* elf/dl-load.c (_dl_map_object_from_fd): Map DSOs with MAP_DENYWRITE.
