No. cysignals is complicated, but it doesn't need dynamic linking to 
Python modules (.so files). It does need "internal" linking: it needs to 
link a non-Cython-generated .c file together with a Cython-generated .c 
file into one Python module. It uses "cdef public" for that, so it would 
run in exactly the problem that this thread is about.

So I personally would not mind if Cython would completely drop support 
for exporting symbols from C extensions (which, AFAIK, doesn't work on 
OS X anyway).
