Most of the code is platform neutral. A few specific bits
(System.Posix, System.Win32) are limited to one operating system, but
that's hardly any of it. If you just write code, there is a strong
chance it will work perfectly on both operating systems. I've only
ever developed Haskell on Windows, and I've never had a Linux user
have a problem with any of it. About the only thing to be "careful"
about with platform differences is that you should make use of the
System.FilePath module to manipulate filepaths, if you are doing that
to any great extent.

If you say what you are tying to do, and why you suspect it might not
"just work" in a cross platform manner, people might be able to
address your specific concerns.
