Works flaky under Windows

[gvanem]

Th README.md doesn't mention if Windows is supported. Since the use or the POSIX headers in the code, one would assume it won't work under Windows at all.

But creating a small Makefile for Cygwin32, it kinda works. Except I get only a result for the final IP (the -p address):

ip2trace.exe -d %APPDATA%/IP2LOCATION-LITE-DB11.IPV6.BIN -p www.cnn.com

I don't think that's the intention. For reference, my own version of a Watt-32 tracert (using IP2Location), shows:

Seems to be an issue with either setsockopt(sockfd, IPPROTO_IP,..) or (mis-)handling of SOCK_RAW sockets under Windows.

Can you make a pull request for these changes? Thanks for your efforts!

[gvanem]

How can I do that when I don't know what the problem is?

It's not tested and optimized under a Windows environment at this moment.
