	[BZ #9957]
	* malloc/malloc.c (force_reg): Define.
	(sYSMALLOc): Load hook variable into variable
	before test and force into register.
	(sYSTRIm): Likewise.
	(public_mALLOc): Force hook value into register.
	(public_fREe): Likewise.
	(public_rEALLOc): Likewise.
	(public_mEMALIGn): Likewise.
	(public_vALLOc): Likewise.
	(public_pVALLOc): Likewise.
	(public_cALLOc): Likewise.
	(__posix_memalign): Likewise.
	* malloc/arena.c (ptmalloc_init): Load hook variable into variable
	before test and force into register.
	* malloc/hooks.c (top_check): Likewise.
	(public_s_ET_STATe): Pretty printing.

	* resolv/res_send.c (send_dg): Don't just ignore the result we got
