	* stdlib/atexit.c (__new_exitfn): Move to cxa_atexit.c.
	(atexit): Implement using __cxa_atexit.
	Use .hidden if availble to avoid exporting atexit.
	* stdlib/cxa_atexit.c (__new_exitfn): Moved to here from atexit.c.
	* stdlib/Versions: Export __new_exitfn for GLIBC_2.2.3.
	* stdlib/Makefile (routines): Add old_atexit.
	(static-only-routines): Add atexit.
