	* stdio-common/scanf11.c: Removed.
	* stdio-common/vfscanf.c Revert patch of Thu Jan 16 23:39:25 1997.
	Although the Corrigendum 1 describes the result as implemented the

	* new-malloc/obstack.h: Don't define malloc using bcopy if malloc
	is not available.  This leads to problems since bcopy does not
	return a value.  Instead define _obstack_memcpy based on memcpy or
	bcopy.  This name isn't used outside obstack.h and so no problems
	from using the memcpy function in a file including obstack.h can
	result.
	Reported by Martin Trapp <trapp@ipd.info.uni-karlsruhe.de>.

	elf_prpsinfo): Likewise.
