:-) I understand the caveats well enough. You can avoid the exceptions very easily using this code:
---8<-------------------------------------- import Foreign.C.Types import Foreign.C.String
foreign import ccall unsafe "HsBase.h __hscore_open" c_open :: CString -> CInt -> CInt -> IO CInt foreign import ccall unsafe "HsBase.h dup2" dup2 :: CInt -> CInt -> IO CInt
open fname oflag pmode = withCString fname $ \c_fname -> c_open c_fname oflag pmode
main = fd <- open "nul" 2 0 dup2 fd 0 dup2 fd 1 dup2 fd 2
I guess Windows can make even Haskell programs look ugly. Or at the very least esthetically unpleasing. :)
... rest of the program goes here. ---8<--------------------------------------
Suggestion for somebody: maybe we should add this (or something such) as standard to the next version of GHC. I mean a proper switch (--mk-gui or something such) and somehow setting the standard handles like above when it's invoked.

When compiling a haskell program under Windows, is there any way to compile it as a GUI program instead of a console program?
Yes, see the following FAQ from Gtk2Hs:
http://haskell.org/gtk2hs/archives/2005/06/23/hiding-the-console-on-windows/
and do make sure you understand the caveats.
