    do not ignore the result of fwrite...
    
    ... at least from compiler point of view.
    On some systems with old glibc (<= 2.15) the fwrite function has
    the warn_unused_result attribute. That makes the build fail.
    Starting with glibc 2.16 the attribute was removed [1].

    The bug: https://sourceware.org/bugzilla/show_bug.cgi?id=11959
    Release notes to 2.16:
