+       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.

        stdio: port --enable-gcc-warnings to clang
        * lib/stdio.in.h (fwrite) [__clang__]: Ignore -Wunused-value entirely,
        since the GCC workaround for fwrite does not pacify clang.
