Update.
1998-09-20 09:37 Ulrich Drepper <drepper@cygnus.com> * elf/Versions [GLIBC_2.1] (libc): Add __fpu_control. * elf/elf.h: Add AT_FPUCW. * elf/Makefile (dl-routines): Add fpu_control. (elide-routines.os): Add fpu_control. (rtld-routines): Add fpu_control. * math/Makefile (aux): Remove fpu_control. * sysdeps/generic/dl-sysdep.c (_dl_sysdep_start): Handle AT_FPUCW. (_dl_show_auxv): Likewise. * sysdeps/unix/sysv/linux/init-first.c (init): Use __setfpucw only if different from OS default. * stdio-common/tstscanf.c: Add test case for (nil).
