an older, slower packet capture mechanism on Linux. Before Linux
2.6.27, the packet ring mechanism uses different-sized kernel
structures on 32- and 64-bit architectures, so a 32-bit program will
not run correctly on a 64-bit kernel. The older mechanism does not
have this flaw.

./configure: line 6651: syntax error near unexpected token `in'
./configure: line 6651: ` for ac_header in'
configure: error: ./configure failed for libpcap

and combine the modification with an existing one for Flex/Bison removal
in NMAP_MODIFICATIONS.
ltmain.sh, and missing from subdirectories. Autoconf automatically looks
in the parent directory for these files. I had to copy the files
depcomp, ltmain.sh, and missing into the root of the source tree.
