Hello Simon,

Also currently broken:
* calling removeFile on a FilePath you get from getDirectoryContents,

Fixing getDirectoryContents will fix these.
no. removeFile like anything else also uses ACP-based api
What code are you looking at?
Here is System.Directory.removeFile:
removeFile :: FilePath -> IO ()
removeFile path =
#if mingw32_HOST_OS
System.Win32.deleteFile path
#else
System.Posix.removeLink path
#endif
and System.Win32.deleteFile:
deleteFile :: String -> IO ()
deleteFile name =
withTString name $ \ c_name ->
failIfFalse_ "DeleteFile" $ c_DeleteFile c_name
foreign import stdcall unsafe "windows.h DeleteFileW"
c_DeleteFile :: LPCTSTR -> IO Bool
note it's calling DeleteFileW, and using wide-char strings.
Windows libraries emulates POSIX API (open, opendir, stat and so on)
by translating these (char-based) calls into A-family. GHC libs are
written Unix way, so these are effectively bundled to A-family of Win
API
Actually we use a mixture of CRT functions and native Windows API,
gradually moving in the direction of the latter.
Cheers,
Simon
