Update.
2000-10-21  Ulrich Drepper  <drepper@redhat.com>

	* elf/dl-open.c (add_to_global): New function.  Split out from
	dl_open_worker.
	(dl_open_worker): Call add_to_global not only for new objects, also for
	previously loaded objects when (mode & RTLD_GLOBAL) and the object
	was not yet in the global scope.
	* elf/Makefile: Add rules to build and run lateglobal.
	* elf/lateglobal.c: New file.
	* elf/ltglobmod1.c: New file.
	* elf/ltglobmod2.c: New file.
