cdef extern from "foo.h":
     cdef struct pair:
         int x
         int y

Sorry, I forgot to say that you should actually define some subset of 
the structure. Otherwise, how will you set and get the members from 
Pyrex code? I'll append the entire file that works for me.

cdef extern from "foo.h":
     cdef struct pair:
         int x
         int y

cdef class Pair:
     cdef pair p

cdef class Fred:
     cdef Pair p

     def __init__(self, Pair p):
         self.p = p

     cdef x(self):
         pass

     def foo(self):
         return self.p.x + self.p.y

def test(a, b):
     return Fred(Pair(a, b))

print test(3, 4)

struct pair{
         int x;
         int y;
};
