Hi All,

Thanks for the analysis.

While this sounds totally brain-dead to me, perhaps there is a simple
solution: take all the generated headers that you are interested in
using, include them into a single header file, and run the pre-processor
on it. This will give you a single (and massive) header without any
includes that you can then try to include into your .cu files.

I don't mind adding work-arounds to XSD as long as they don't make
the code unmaintainable. At this stage, we don't even know what they
are.
