Hi,
this bug makes haskell-glut FTBFS and is forwarded upstream as
http://trac.haskell.org/haddock/ticket/194, this is just for reference:
Hi,
this is Haddock version 2.10.0 as shipped with GHC 7.4.1. The package
GLUT-2.1.2.1 contains FFI code that GHC warns about, but haddock fails:
[ 9 of 21] Compiling Graphics.UI.GLUT.Window (
Graphics/UI/GLUT/Window.hs, dist-ghc/build/Graphics/UI/GLUT/Window.o )
Graphics/UI/GLUT/Window.hs:113:1:
Warning: newtype `Window' is used in an FFI declaration,
but its constructor is not in scope.
This will become an error in GHC 7.6.1.
When checking declaration:
foreign import ccall unsafe ""static glutCreateWindow""
glutCreateWindow
:: CString -> IO Window
vs.
Running Haddock for GLUT-2.1.2.1...
Running hscolour for GLUT-2.1.2.1...
Preprocessing library GLUT-2.1.2.1...
Warning: The documentation for the following packages are not
installed. No
links will be generated to these packages: rts-1.0
Preprocessing library GLUT-2.1.2.1...
[..]
Graphics/UI/GLUT/Window.hs:113:1:
Unacceptable result type in foreign declaration: IO Window
When checking declaration:
foreign import ccall unsafe ""static glutCreateWindow""
glutCreateWindow
:: CString -> IO Window
But something is fishy, the [..] part contains a few of the Warning: newtype
`CInt' is used in an FFI declaration, warnings, so maybe something else is
amiss here.

No GHC does reject such types as well.
