* 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.
