Thanks for the report. It's good to know what people are trying this and finding the obvious deficiencies :-)
It's slightly harder than it looks. Cython doesn't actually know a lot about integer typedefs - mostly just that it's "some integer" and whether it's signed or not. However, it needs to tell Numpy exactly what type is actually being used. So it either needs some special-casing for these Numpy typedefs, or it needs a clever runtime mechanism to work out what to tell Numpy.
