That *does* in fact seem to be a recurring problem, yes.

Now, how to fix this...?

I did try to get wxHaskell going once or twice. And the SDL binding. (I 
wasn't aware we have Qt now...) I've never got any of them to work yet. :-(

Interestingly, while you can't compile bindings to external C libraries, 
GHC does appear to ship with all the header files for Windows, which is 
odd. It seems if you try to FFI to a standard Win32 function, it 
magically knows where the hell the header files are, and it Just 
Works(tm). Hell, I even followed a C++ guide to Win32 programming and 
managed to translate an "open a blank window" program to Haskell, and it 
worked. Maybe somebody just needs to sit down and write a nice binding 
for doing native GUI stuff under Win32?
