I am sure that I am loading the right dll (it is in my workind directory, 
and I have changed the mainLoop C function to print a message on the 
console, and it does).
I was a bit confussed as function "glutVersion" was reporting "GLUT 3.7", 
but that is because it is just guessing and getProcAddressInternal is not 
working. To confirm this, I got a copy of Extension.hs and loaded it:

ghci -package GLUT -fffi Extensions.hs

then I get:

*Graphics.UI.GLUT.Extensions> getProcAddressInternal "glutSetOption"
0x00000000
*Graphics.UI.GLUT.Extensions> getProcAddressInternal 
"glutSetWindowStayOnTop"
0x00000000

By the way, I get the same behaviour when using the original glut32.dll.

Any help?
