No need to CC me as I'm subscribed.

I'm not a C programmer either, so caveats apply.

The only use of answerlen is the one that causes the build failure:

#ifdef T_RRSIG
                else if (type == T_RRSIG)
                {
                        GETSHORT(answerlen, cur_ptr);
                        cur_ptr += answerlen;
                }
#endif /* T_RRSIG */

I don't get it on Debian, so maybe there's a different option enabled, but I 
didn't figure out what.  I checked, and no where in opendmarc is answerlen 
defined, so I think the error is correct.  I do not that answer_len is both 
defined and used, so maybe that's what it's supposed to be there.
