patch applied (cabal): Extend and use the OS data type in the package description

Mon Mar 3 12:03:38 PST 2008 Duncan Coutts * Extend and use the OS data type in the package description Rather than just using a string. This makes comparing OSs easier since we can normalise them once when we parse rather than every time we compare. Also makes it easy to discover when a package mentions an unknown OS since it's marked as Other "whatever".
