Doing so on Windows is a real pain since there isn't a straight forward make file for MinGW. It seemed mostly geared at Microsoft VC.
Just copy and paste the following text into a "makewin.cmd" file in the same directory as the source. A good place to get source for Windows is http://joncraton.org/blog/46#comment-14590181 (this also includes a binary for Netcat for Windows but the -e option is still turned on). I also have a build of Netcat that you can download here. In addition you can find other sites that provide mirrors at http://www.thaoh.net/Tools/Netcat/
You'll need MinGW with gcc version 3.4.5 (I used MinGW 5.1.4. Modify the paths in the batch script as needed and run it. You should get a nc.exe file if all went well. If not feel free to drop me an e-mail at website2008+netcat -AT_NOSPAM- rodneybeede _D0t_ com.
