You'll need to put declarations in there for the
functions you want to use from math.h, e.g.

   cdef extern from "math.h":
     double sqrt(double)

That's because the 'cdef extern from' statement needs
a suite after it. If you really need an empty one, you
can put 'pass' in the body, but that's almost always
useless.
