The issue is that cabal-install- is broken on Windows. We have a
new, fixed cabal-install- out, but if you were unlucky enough to
install the broken one you need to delete that binary and install
cabal-install again (either by using the bootstrap.sh script in the
cabal-install repo or by some other means).
