Somehow I really gave off the wrong impression. Windows is most
definitely not my favorite platform. My primary development computer
is currently a MacBook, and my secondary system runs Linux. I'm
advocating for Windows for two reasons:
1. There are a non-trivial number of Windows Haskellers, and they
frequently post about problems on this list. I would like to make
their lives a little better..
2. A substantial portion of computer users are on Windows. If I want
them to use my software, or even expose them to the glory of Haskell,
I need to speak their language.
A possible third reason is that I have used some number of
gnu-toolchain-developed programs on Windows (using mingw), and the
experience is frequently miserable. Graphics libraries lag, all sorts
of configuration errors, missing packages, etc. Compared to that, the
GHC compiler chain and libraries are fantastic. It pretty much works,
and I think it can be better. I would like to see a wider adoption of
Haskell in general, and improving Haskell support for windows is would

I think Haskell is a lot closer to this than many other languages.
Generally, Haskell packages that don't work on Windows fall into one
of three categories:
1. Packages that link to a C library, in which case it depends on the
2. Packages that are closely tied to Unix/Posix.
3. Packages that depend on one of the above (or another in this category).
It's the third category that's mostly under discussion here. If
Package A is posix-dependent, but a cross-platform alternative is
available, then by using the cross-platform alternative Package B
really can get Windows compatibility for free (assuming equivalent
functionality between alternatives). I really don't see anything
wrong with using Hoogle to increase awareness (although I would
appreciate it if platform-specific packages were searched as an
