Win64 support

Hello glasgow-haskell-users, the one thing that users of my program asked most is the Win64 support: http://code.google.com/p/freearc/issues/list . we have waited for a several years, but it's still not in GHC, so i want to know at least: why it's not going forward? can we have unregisterized build at least? -- Best regards, Bulat mailto:Bulat.Ziganshin@gmail.com
