The Right Thing is to generate C wrapper functions which use const as 
appropriate.  GreenCard can do this and I believe HDirect can too.

However, the 80% solution is a lot less work.  Compiling the C code generated 
by your Haskell compiler with -Dconst is a good way to suppress these 
warnings.  Of course, there is a risk that some of the warnings are about a 
real problem...
