	reports out of the database).

1998-05-27  Mark Kettenis  <kettenis@phys.uva.nl>

	* mach/Machrules: Use $(move-if-change).

1998-05-27  Mark Kettenis  <kettenis@phys.uva.nl>

	* Makeconfig [elf=yes] (+interp): New variable, set to interp.os.
	* Makerules (lib%.so): Depend on $(+interp).
	(libc.so): Add interp.os to list of dependencies.
	(interp-obj): Remove variable.
	* mach/Machrules (+interp): Define to empty since libhurduser and
	libmachuser don't need to have the interpreter set.

1998-05-28  Andreas Jaeger  <aj@arthur.rhein-neckar.de>

	* resolv/res_send.c: Security fixes from bind 4.9.7-REL.

	* resolv/gethnamaddr.c: Likewise.

	* resolv/res_comp.c: Likewise.

1998-05-28  Mark Kettenis  <kettenis@phys.uva.nl>

	* sysdeps/mach/hurd/wait4.c (__wait4): Use ANSI-style definition
	so that transparent union works.
