This warning does not mean that the Cython declaration doesn't match
the C declaration (Cython knows nothing about the C declaration).
Instead, it means that there are two Cython declarations that don't
match.  Search all your .pxd and .pxi files for another declaration of
iw_img_new_alloc; also, make sure that Gimage.pxi is not included
multiple times.
