A long is only machine word wide on posix, in windows its not. This
nonsense is unfortunately also in numpy. It also affects dtype=int.
The correct word size type is actually np.intp.
btw. if something needs deprecating it is np.float128, this is the most
confusing type name in all of numpy as its precision is actually a 80
bit in most cases (x86), 64 bit sometimes (arm) and very rarely actually
128 bit (sparc).
