	* sysdeps/mach/hurd/Makefile (rpcuserlibs): New variable.
	($(common-objpfx)libc.so): Move deps into that, use it.
	[$(subdir) = elf] ($(objpfx)librtld.so): Depend on
	$(rpcuserlibs:.so=_pic.a).
	* elf/Makefile ($(objpfx)librtld.so): Just depend on libc_pic.a; don't
	use $(LDLIBS-c.so).

Thu Jul 18 21:41:25 1996  Andreas Schwab  <schwab@issan.informatik.uni-dortmund.de>

	* sysdeps/generic/stpncpy.c: Fix semantics to make `stpncpy (d, s,
 	n)' equivalent to `strncpy (d, s, n), d += strnlen (d, n)'.
