Why do the guards need to be stripped?

I can't say (not familiar with cffi), but the tests fail when they're there and pass when they're not. I assume it's for the same reason that include statements (and friends) are stripped

When using the numpy.random C API with Cython as described in examples with C++ sources instead of C sources, C++ name mangling will prevent correctly linking to symbols in the
npyrandomstatic library which has C linkage. A work-around is described here, but it seems like adding someextern "C"declarations should do the trick. These are found in nearly all other numpy header files, e.g. npy_math.h.Someone else may need to comment on why
cffiextending tests are failing, I am unfamiliar withcffi. EDIT: filtering outextern "C"statements was enough to get the tests working
