4843	"""include"" directory missing in the ghc 7.0.1 windows installer"	nsch		"The current windows installer from http://www.haskell.org/ghc/download_ghc_7_0_1#windows is missing the ""include"" directory in its root directory.

For example this build fails because it cannot find '''HsFFI.h''', which is located in `C:\Haskell\ghc-7.0.1\lib\include` and not in `C:\\Haskell\\ghc-7.0.1/include`, where GHC is looking for it:
