Hey, when I said the windows 64 bits support was experimental, I meant it :)

There was a bug in the mingw powl function, but I thought the problem
was fixed upstream. I will look at it.
This shows that numpy lacks long testing, though - the numpy test
suite passes 100 % (when it does not crash :) ), but the long double
support is very flaky at best on the windows 64 + mingw combination
ATM.
cheers,
