GHC build break in Win32Spawn.hs

Has anyone lese noticed this build break when building GHC for Windows?

Win32Spawn.hs:38:14:
    Couldn't match `IO Handle' against `t -> t1'
      Expected type: IO Handle
      Inferred type: t -> t1
    Probable cause: `openFd' is applied to too many arguments in the call
        (openFd (fromIntegral wIn)
                (Just RegularFile)
                False
                ("<fd " ++ ((show wIn) ++ ">"))
                WriteMode
                False
                False)
    In a 'do' expression:
        hIn <- openFd (fromIntegral wIn)
                      (Just RegularFile)
                      False
                      ("<fd " ++ ((show wIn) ++ ">"))
                      WriteMode
                      False
                      False
make[2]: *** [Win32Spawn.o] Error 1
make[1]: *** [all] Error 1
make[1]: Leaving directory `/c/src/ghc/fptools/hslibs'
make: *** [build] Error 1
