* include/unistd.h: Uncomment libc_hidden_proto for _exit.
* sysdeps/mach/hurd/_exit.c: Add libc_hidden_def. * sysdeps/generic/_exit.c: Likewise. 2002-09-12 Jakub Jelinek <jakub@redhat.com> * elf/rtld.c (struct dl_start_final_info): New. (_dl_start_final): Change second argument to struct dl_start_final_info *. Set start_time from info. (_dl_start): Remove bootstrap_map variable, add info. Define bootstrap_map as macro. If not DONT_USE_BOOTSTRAP_MAP, store HP_TIMING_NOW result into info.start_time.
