Update.
1998-10-08 Paul Eggert <eggert@twinsun.com> * time/mktime.c (my_mktime_localtime_r): Renamed from localtime_r. Define also if HAVE_LOCALTIME_R && defined localtime_r, with a body that merely expands localtime_r; this works around a bug in Digital Unix 4.0A and 4.0D. 1998-10-14 Ulrich Drepper <drepper@cygnus.com> * sysdeps/unix/sysv/linux/powerpc/syscalls.list: Add s_ioctl. * sysdeps/unix/sysv/linux/powerpc/tcgetattr.c: New file. Define __ioctl to __syscall_ioctl and include Linux version of this file. * sysdeps/unix/sysv/linux/powerpc/tcsetattr.c: Likewise. * sysdeps/unix/sysv/linux/powerpc/ioctl.c: New file. Redirect ioctl calls which handle struct termios. Based on a patch by Dan Jacobowitz <drow@false.org>.
