There isn't really much to write up. All that needs to be done is open up the vcxproj files and change the lines 
"<PlatformToolset>v120</PlatformToolset>” to "<PlatformToolset>v120_xp</PlatformToolset>”. That’s it.

I downloaded nmap-6.49BETA4 and tested this. It compiled fine and no source code changes were needed. The resulting 
nmap.exe runs fine on XPsp3. Given that it’s such a trivial change, why not support it?

I’d be happy to contribute a pull request.. or however that is done with SVN.
