Since people had sometimes problems building Haskell executables we use in EclipseFP, I thought I'd help by putting versions of the current Windows executables on sourceforge. So in you run Windows and have trouble building scion-browser or buildwrapper, you can grab them from here.
I know this isn't really in the spirit of "build from sources so you can check them yaddi yadda", but since even Cabal does it...
As usual, use at your own risk, etc.
Happy Haskell Hacking!
