    This patch lets aggdraw compile and work fine for my requirement. But
    I haven't extensively tested it. YMMV.

Thanks! This solution saved me!

I re-posted your solution to my blog because blogger seems to have mangled your diff a bit. I hope that's ok.

I would recommend casting to size_t, not unsigned long, that way you're not changing the behavior on i386.
