Add some missing/wrong dependencies. Show how to respect CC/CFLAGS. Many
miscellaneous modifications. I used more excessive hacks to force p5-Jcode
and p5-WWW-Search to respect CC/CFLAGS.
Patches largely done by: Christian Weisgerber <naddy@mips.inka.de>
in traditional address/netmask format and in the new CIDR format.
Methods for calculating the network and broadcast address, and
also to check if a given address is in a specific network also exist.
