[jhc] Compile OpenGL for jhc

Hi! As OpenGL haskell binding depends only on base, it would be great to compile it with jhc. I've tried to do that, but I had some problems with preprocessor directives. It would be also great to add jhc support for OpenGL bindings build scripts. Or, it would be better to add jhc support for cabal-install. :) Is there anyone who has any idea any of this things? (for soulution)
