d3162773d5 arping: move packet buffer, sigset and struct ifreq to malloced "globals" 
This way, we can zero them all in one go.
We do malloc() anyway, thus nothing is lost by mallocing "globals"

it could sometimes treat newlines as if they are spaces.

2598915d43 gunzip: fix from gzip-1.3.12 for gzip file with all zero length codes 
Corresponding changelog from gzip-1.3.12 reads:

"""
2006-12-20  Paul Eggert  <eggert@cs.ucla.edu>
        * inflate.c (huft_build): Fix regression that caused gzip to
        refuse to uncompress null input (all zero length codes).  Problem
        reported by Yiorgos Adamopoulos.  This regression was caused by
        the security patch installed 2006-11-20, which in turn came from
        Debian, which in turn apparently came from Thomas Biege of SuSe.
