o Removed config.sub, config.guess, install-sh, ltmain.sh, and missing from the
  config directory. These files are found in the parent (i.e., Nmap's)
  directory. Also removed config/mkinstalldirs because it is replaced with
  $(install_sh) -d. Change Makefile.am not to use ac_aux_dir, which is an
  internal Autoconf variable.

o Remember the entry->intf_len before zeroing entry in _ifrow_to_entry.
intf_loop relies on passing the length inside the structure to make sure
interface aliases are accounted for.

avoid accessing uninitialized memory when an unknown device name is
