It is not quite operational for Windows in 6.x. In GRASS 7, it has been
rewritten in Python (I still vote for backport) with the hope that it is
portable.

Using my preferred search engine, I found quite some results.
Perhaps you can take a look, it looks like a (local) MinGW problem
to be solved before trying to compile Addons.
