In proposed change to py_kcluster in this patch, using npy_generic_dimension_t
for nrows, ncolumns will cause a bug.

Depending on the platform, npy_genetic_dimension_t may not be an int. But the
function kcluster, which is called from py_kcluster, expects nrows, ncolumns to
be an int. If, for example, npy_genetic_dimension_t is an 8-byte long, nrows
will be truncated to a 4-byte int in the call to kcluster. So kcluster may get
an incorrect number for nrows, ncolumns.
