  Modified files:
    ghc/lib/std          IO.lhs PrelHandle.hsc PrelIOBase.lhs 
  Log:
  More fixups to make the new IO lib work on mingw.
  * Outlaw changing the file position on a text-mode file.  After
    consideration of the mingw translation semantics I cannot see
    how to make a correct implementation.
  * Add a field to Handle__ to say whether or not the handle is in
    binary mode.
  * Restrict seek operations on Handles to those in binary mode.
  * Export hSetBinaryMode from IO.lhs.
