[Ns-developers] Compilation on MinGW-x64

[Josh Pelkey]

Unfortunately as an "unofficially supported" platform, we are too late
in the release cycle to fix this one.  I would be tempted to do it if
the patch was the only thing needed, but it looks like a different WAF
binary is needed too.  May 3, the dev branch is open again, and I
recommend reviving this discussion if mingw is something you would
like to see building ns-3 again.
