Yes, I saw that. My C is rusty, but wouldn't the cast take care of it?  
n is of type size_t, which is pretty big, and a cast to long shouldn't  
be an issue. And if (hopefully) PyErr_Format is correct...

At any rate, I am without an account on those machines, so I will have  
to try and reproduce it elsewhere, or else do this in an extremely  
annoying fashion by proxy.

I should've mentioned this is with the 1.3.0 release, not that it's  
changed since.
