Thanks. The only problem is that dlltool doesn't work because I don't have 
cygwin installed. (I just downloaded dlltool.exe from somewhere on the web) 
I really don't want to install cygwin if at all possible because I'm trying 
to keep my system as close as possible to an end-user's system ie just winXP 
and nothing else (except VS and GHC) - is there a version of dlltool that 
can just run by itself?
