	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.
