[Haskell-cafe] I read somewhere that for 90% of a wide class of
computing problems, you only need 10% of the source code in Haskell,
that you would in an imperative language.

This is a problem of C / Posix, not a problem of Haskell. Haskell C
bindings compile on Windows without issues IF the corrisponding
library is available. It is compiling the (usually posix) C library in
Windows the real issue.
Anyway, on Windows Vista, cmd.exe:
GHCi, version 6.10.4: http://www.haskell.org/ghc/ :? for help
Prelude> :m System.Directory
Prelude System.Directory> doesDirectoryExist "C:\\"
