commit 9c65eec494676789bc4695561e229ce3ee33be84

    Fix sigevent namespace (bug 21543).

    signal.h defines the sigevent structure and constants if defined
    __USE_POSIX199309 || defined __USE_XOPEN_EXTENDED.  The
    __USE_XOPEN_EXTENDED condition is incorrect; this structure does not
    appear in XSI standards before Unix98 (which implies
    __USE_POSIX199309).  This patch fixes the conditionals accordingly
    (the existing conditional is correct for siginfo_t, just not for
    sigevent).

    Tested for x86_64.  This does not allow any conform/ XFAILs to be
    removed because of other signal.h namespace bugs.

        [BZ #21543]
        * signal/signal.h: Only include <bits/types/sigevent_t.h> and
        <bits/sigevent-consts.h> if [__USE_POSIX199309], not if
        [__USE_XOPEN_EXTENDED].
