You should be able to get a much more up to date mingw by following instructions at, http://win-builds.org/doku.php.

The instructions at http://win-builds.org/doku.php/download_and_installation_from_linux yielded what I remember as a gcc 4.9 for a linux -&gt; windows cross compiler.

Judging from the success there, I suspect the windows instructions at http://win-builds.org/doku.php/download_and_installation_from_windows will work. (linked from http://win-builds.org/doku.php/download)



Indeed, the gcc should be even newer by now.
