[Cython] cdef public declarations

(this thread is related to the thread "Question about how best require compiler options for C sources") I have a question for Cython users and developers: are you sure that "cdef public" actually works as documented at http://docs.cython.org/src/userguide/external_C_code.html#public-declaration... I couldn't find it tested in the Cython testsuite, although it's not easy to know what to grep for. I hightly doubt that it works on OS X because of the difference between shared libraries (with .dylib extension) and loadable modules/bundles (with .so extension).
