Hi! It's perfectly normal, to use that gcc. What it should do is to check out the ghc-tarballs repo and unpack a gcc from there. Now that I think of it, I had to manually get that repo last time. Maybe sync-all is broken? .

I had to copy my entire mingw installation there to get it to configure. This isn't normal, right? Regards.
