 <roland@delasyd.gnu.ai.mit.edu>

	* time/strftime.c (strftime: do_number): Adjust P and I after sprintf
	in case it wrote fewer than MAXDIGITS chars.

	* stdio/fwrite.c (fwrite: fill_buffer): Separate flushing for last
	newline from flushing full buffer in loop, fix test so no fflush is
	done when last byte written exactly fills the buffer.

	* nss/Makefile ($(services:%=$(objpfx)libnss_%.so)): Depend on libc.so.

	* sysdeps/mach/hurd/Makefile (LDLIBS-c.so): Variable removed.
	(libc.so): Instead, give this deps on lib{mach,hurd}user.so.

	* elf/dl-debug.c (_dl_debug_initialize): Use LDBASE arg instead of
	extracting _dl_rtld_map.l_addr.

	* sysdeps/i386/dl-machine.h (elf_machine_rel): Declare _dl_rtld_map as
	weak.
	* sysdeps/alpha/dl-machine.h (elf_machine_rela): Likewise.

	* shlib-versions (*-*-*): Set libnss_db=1.

	* elf/rtld.c (dl_main): Set _dl_rtld_map's DT_DEBUG location too.
