It looks like sparse.h contains function prototypes that are never
defined in a .c file.  You should be able to just delete them from the
header files.

Nils, have you considered using NumPy's IO capabilities instead of
using this code?  I find IO to be a place where implementing from
scratch with Python + NumPy is often easier and just as fast.   Plus,
you end up with a .py that's easy to share with others.
