You can create a DLL of Haskell code on Windows, but only of a complete
self-contained library (ie. you can't split your Haskell library into
several DLLs and link them together at runtime).
On Unix, shared libraries are more difficult. It might be possible to
make a single .so of a Haskell library, but I'm not sure. Alternatively
you can use Don Stewart's hs-plugin package (announced here recently).
Cheers,
