That's okay too.  The function could be PyInt_AsUnsignedLong().  It
could convert negative 32-bit ints to unsigned as a backward
compatibility measure (with warning?) that will eventually disappear.

The format code could be 'I' for unsigned int, but I don't know what
to use for unsigned long.  Or perhaps still use 'k'/'K' for masK?
