MaraDNS Halloween snapshot

I have uploaded a new snapshot of MaraDNS today. This snapshot is a snapshot of the work I have done so far porting Deadwood to Windows. The UDP client works; the TCP client, however, has problems which I am still debugging.

Windows sockets are somewhat different from *NIX sockets; I have been reading the Winsock Programmer's FAQ and have downloaded Visual Studio C++ express with all of the MSDN documentation, which will hopefully give me the Windows version of things like "man 2 select".

Some of the *NIX code looks different since I'm making Deadwood portable. There is not a fcntl() visible in the main code; instead I have a macro, make_socket_nonblock() which does the right thing in both *NIX and Windows. There are some other changes: Sockets are not ints, but SOCKETs in Windows; you don't close() a socket, but closesocket() it. An error for sockets is INVALID_SOCKET. There's no inet_aton(), much less inet_pton(), so I just wrote a wrapper for inet_addr() that acts like inet_pton(). The socket code now looks like a strange mixture of Windows and *NIX socket code, with #defines in DwSocket.h making the Windows code look like *NIX code, and making the *NIX code look like Windows code.

My current project is to fix the TCP code in Windows.

As an aside, XP service pack 2 only has one loopback IP address, but Microsoft has a hotfix that fixes this issue; I needed to do this so I can test MaraDNS when offline.

You know, it's a mystery to me why IPV6, out of its 340282366920938463463374607431768211456 possible IPs, only allocates one for loopback. I mean, they could have allocated 16 IPV6 IPs for loopback; I'm sure 340282366920938463463374607431768211440 IPs is enough for non-loopback use.

Anyway, the latest snapshot can be downloaded here.
