Yes, and there are various other reasons too. There's a FAQ question in GHC's (rather well hidden) FAQ: http://www.haskell.org/ghc/docs/latest/html/users_guide/faq.html and a search through the glasgow-haskell-users archives will turn up previous discussions. Also, we do (or did) have support for dynamic libraries on Windows.
