From: Ulrich Drepper <drepper@redhat.com>

Subject: * stdlib/Makefile (routines): Add quick_exit, at_quick_exit, and

	cxa_at_quick_exit.
	(static-only-routines): Add at_quick_exit.
	* stdlib/Versions: Export quick_exit and __cxa_at_quick_exit for
	GLIBC_2.10.
	* stdlib/quick_exit.c: New file.
	* stdlib/at_quick_exit.c: New file.
	* stdlib/cxa_at_quick_exit.c: New file.
	* stdlib/cxa_atexit.c (__cxa_atexit): Move body to new function.  Call
	it appropriately.
	(__internal_atexit): New function.
	(__new_exitfn): Now takes parameter to point to the list to use.
	* stdlib/cxa_finalize.c: Remove quick_exit handlers, don't call them.
	* stdlib/exit.c (__run_exit_handlers): New function.  Split from...
	(exit): ...here.  Just call __run_exit_handlers appropriately.
	* stdlib/exit.h: Declare __quick_exit_funcs, __run_exit_handlers,
	__internal_atexit, __cxa_at_quick_exit.  Adjust __new_exitfn.
	* stdlib/on_exit.c: Adjust call to __new_exitfn.
	* stdlib/stdlib.h: Declare at_quick_exit and quick_exit.
