Thanks, I'll use that!

Program Files\Haskell is what cabal-install uses by default. 

I decided to use $SYSTEMDRIVE\ghc for GHC just in case it has
objections to being run from a directory with spaces in it.

If there's a demand for "Install only for the current user"
feature, then the only safe choice is $HOME. For example, at my
school Windows machines are configured so that ordinary users
can't write to C:\.
