[Haskell-cafe] OS X ghci problem

[Carter Schonwald]

Christian,
Yes, ghc 7.7/7.8 *should* fix all the ghci linker related problems on
platforms that support dynamic linking!

If (or anyone else) finds problems with the ghci linker on 7.7, please
report them post haste!

I'm also glad to hear that someone's finally tested out the new ghci
functionality properly!

-Carter
