Simon recently collected all the pieces needed for GHC builds on
windows, so -in principle- someone could make a cabal package
that downloads and installs these pieces in their default location
and then cabal could implicitly depend on that package if seeing
a package using 'build-type: configure' on Windows. That would
solve this particular issue for all cabal packages. And once GHC
becomes able to use a standard MinGW layout
it could also depend on such a tools package.
That is assuming the licenses are favourable for redistribution,
and the installers can be run from the commandline.
PS. of course, unnecessary dependencies aren't necessary;-)
