Err, for maximum portability you can use the int64 constructor:
>>> type(np.int64(2))

The cython function below returns a long int:
@cython.boundscheck(False)
def mysum(np.ndarray[np.int64_t, ndim=1] a):
"sum of 1d numpy array with dtype=np.int64."
cdef Py_ssize_t i
cdef int asize = a.shape[0]
cdef np.int64_t asum = 0
for i in range(a
