* 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.
