It compiles fine on plain FreeBSD because <sys/nlist_aout.h> checks if
<a.out.h> has been included before and defines the structure differently
in that case.

<sys/nlist_aout.h> has to be modified for GNU/kFreeBSD, that is by 
checking for __A_OUT_GNU_H__ instead of _AOUT_INCLUDE_ and by defining
the first part of the structure the same way as in the GNU libc (that is
by using a transparent union).

I am therefore reassigning the bug to kfreebsd-kernel-headers.
