I have sent a patch:

Thu Oct 29 08:19:03 1998  H.J. Lu  <hjl@gnu.org>

        * sysdeps/unix/sysv/linux/bits/sigaction.h (sigaction): Use
        union only if __USE_POSIX199309 is defined.

What happened to it? In fact, I have sent quite a few patches. Most
of them are not in the current glibc 2.1.
