	DL_LOOKUP_NOEXEC as second argument to the RESOLVE macro if
	processing a copy reloc, DL_LOOKUP_NOPLT for a jump slot
	reloc, zero otherwise.
	* sysdeps/alpha/dl-machine.h (elf_machine_rela): Likewise.
	* sysdeps/i386/dl-machine.h (elf_machine_rel): Likewise.
	* sysdeps/mips/dl-machine.h (elf_machine_rel): Likewise.

Tue Aug 13 00:55:03 1996  Andreas Schwab  <schwab@issan.informatik.uni-dortmund.de>

	* shadow/sgetspent_r.c (__sgetspent_r): Copy string to buffer, not
	the other way round.

	* resolv/Makefile (libresolv-routines): Add base64, inet_net_ntop,
 	inet_net_pton, inet_net.
	* resolv/arpa/nameser.h (__BIND): Update version number.
Mon Aug 12 19:03:22 1996  Thomas Bushnell n/BSG  <thomas@psilocin.gnu.ai.mit.edu>

	* sysdeps/generic/gnu/types.h: Declare __fd_mask as `unsigned long'.

	* mach/Makefile (mach/mach_host.uh): Depend on
 	$(objpfx)/mach-syscalls.mk.
	($(objpfx)mach-shortcuts.h): Depend on $(objpfx)mach/mach_host.h.
