Would this do the trick ? Or do you want to use the "true" ssize_t,
even in older Python's ??
cdef extern from *:
ctypedef int ssize_t "Py_ssize_t"
The Py<->C conversion should not used the Index C-API calls, and
should be platform-agnostic (because of my patch for extern ctypedef
integrals).. Take a look at the code generated from the snippet below:
cdef extern from *:
ctypedef int ssize_t "Py_ssize_t"
def test_ssize_t(a, b, c):
"""
>>> test_ssize_t(4.0, 3, -2)
(4, 3, -2)
"""
cdef ssize_t x = a
cdef ssize_t y = b
cdef ssize_t z = c
return (x, y, z)

So we really need it? I think now it is not essential... But I would
like to have it anyway, just for symmetry with size_t ...
What do you thing about aliasing the Cython-level ssize_t to the
C-level Py_ssize_t?
