GSoC community ideas/Port Nmap to MinGW

Building Nmap on Windows currently requires Microsoft Visual Studio. It would be great to make the whole Nmap project (including Nbase and Nsock libraries and umbrella projects such Nping, Ncat etc.) build under MinGW to get rid of proprietary dependencies, make it easier to cross-compile and simplify the build process.

• Related: http://seclists.org/nmap-dev/2013/q3/321 - if I recall David's comments correctly, the GSoC project would have to port all the Nmap codebase, not just Ncat and avoid cryptic #ifdefs, making it clear why particular solutions were chosen.
