[Haskell-cafe] Hint causes GHCi linker error under Windows

Hi Daniel,

With this code I could reproduce it in ghci.

Currently I am not on a Windows machine, so I can't tell you if this
only occured when trying to load a specific module. I'll try it later
and if so, I'll tell you.

If you need more information, just let me know.
