2004-03-24 Jakub Jelinek <jakub@redhat.com> * stdlib/strtod_l.c (INTERNAL (__STRTOF)): Clear the rest of retval, not just one limb if RETURN_LIMB_SIZE > 2. Fix shifting up if RETURN_LIMB_SIZE > 2. * stdio-common/printf_fp.c (__printf_fp): For IEEE quad long double on 32-bit architectures reserve 8 limbs instead of 4.
