Sorry for response late.
The preprocessor problem is solved now, I don't know why Intel compiler
doesn't accept such kind of definitions. But if you use the latest
trunk, it should work.
I'm working on the import/export problem, and trying to fix it with a
better mechanism. I'll let you know when it's ready.
