More work towards dynamic programs on Windows
Dynamic GHC is now working in-place, but pathologically slow due to the DLL split. (GHC assumes that all intra-package calls are in the same DLL, but that isn't true when we split the GHC package into 2 DLLs. That means that GHC's startup time is around 22 seconds, as it is doing run-time linking). Also, ghci isn't actually working yet: $ inplace/bin/ghc-stage2 --interactive GHCi, version 7.7.20130512: http://www.haskell.org/ghc/ :? for help Loading package ghc-prim ... <command line>: can't load .so/.DLL for: HSghc-prim-0.3.1.0.dll (addDLL: could not load DLL) ghc-stage2.exe: HSghc-prim-0.3.1.0: The specified module could not be found.
