commit 9d52cb01f253c84e177fe2db8386deaea06a2596
Author: Florian Weimer <fweimer@redhat.com>
Date:   Thu Jun 23 11:01:21 2016 +0200

    test-skeleton.c: xmalloc, xcalloc, xrealloc are potentially unused
    
    __attribute__ ((used)) means that the function has to be
    emitted in assembly because it is referenced in ways the
    compiler cannot detect (such as asm statements, or some
    post-processing on the generated assembly).
    
    The unused attribute needs to come first, otherwise it is
    applied to the return type and not the function definition.
