well, IIUC,  np.int is the python integer type, which is a C long in all the implemtations of cPython that I know about -- but is that a guarantee? in the future as well? For instance, if it were up to me, I'd use an int_64_t on all 64 bit platforms, rather than having that odd 32 bit on Windows, 64 bit on *nix silliness....

So another minor proposal: add a numpy.longc type, which would be platform C long. (and probably just an alias to something already there).
