"include" directory missing in the ghc 7.0.1 windows installer

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:

configure: creating ./config.status
config.status: creating include/HsDirectoryConfig.h
config.status: include/HsDirectoryConfig.h is unchanged

You have to pass --extra-include-dirs=C:/Haskell/ghc-7.0.1/lib/include to get it to compile.
