--- Comment #2 from Christopher Wecht <wechtc at gmail.com> ---
There is another problem with this function. Pointer arithmetic  on void
pointers in illegal in either C and C++, it is an extension of GCC:
https://gcc.gnu.org/onlinedocs/gcc-4.8.0/gcc/Pointer-Arith.html

To be compliant to both standards, the expression should look something like
this.

return (xt_entry_target *)((char *)e + e->target_offset);
