Hm, this actually is supposed to work.  Could you please re-run this
procedure with the original path and with maximum verbosity?  I.e.:

  > runhaskell Setup configure -v3

In any case though, if you have problems with Cabal or cabal-install,
send a bug report -- Windows might not be number one priority (since
most of the developers don't use it (often)) don't expect us to fix bugs
that we don't know about.  (Naturally.)
