stdio: use __REDIRECT for fwrite, fwrite_unlocked * lib/stdio.in.h (fwrite): When working around bug 11959, use __REDIRECT rather than '#define fwrite(...) ... fwrite (...) ...'. This is a more-targeted way to fix the -Wunused-value issue with clang, and it works with GCC too. Problem with targeting reported by Eric Blake in <http://lists.gnu.org/archive/html/bug-gnulib/2013-05/msg00067.html>. (fwrite_unlocked): Treat like fwrite. I ran into this issue while debugging the fwrite issue.

/* Wrapper to implement ANSI C's atexit using SunOS's on_exit. */
/* This function is in the public domain.  --Mike Stump. */

int
atexit (void (*f) (void))
{
  /* If the system doesn't provide a definition for atexit, use on_exit
     if the system provides that.  */
  on_exit (f, 0);
  return 0;
